OpenFur: Large Canine Fursuit Head

prusaprinters

<h3>Preface</h3> The entire project is still a work in progress and instructions are subject to change. I also plan to add claws and a tail holder later.This head was designed specifically for smaller printers, with a minimum build area of 18cm x 18cm x 18cm and to use comparatively little filament (<200g), while still holding up against accidental abuse. If you don't own a 3D printer but have seen this blank somewhere else and want to use it, I recommend just asking in a furry group chat on a platform of your choice. Many furries are also tinkerers and will print this for little money.The base (including teeth, gums, tongue and nose) should cost about 6€ ($7) (plus a bit more if you have someone else print it). This of course will depend on the filament used. Additionally you will need the parts listed in the BOM below. Their cost may wary, especially when it comes to the fur, which will probably be the most expensive part. <h3>Bill Of Materials (head only)</h3> <ul><li>this base (I recommend PETG for printing).</li><li>plastic glue (which bonds well with the filament and preferably has a needle applicator)</li><li>2x 5mm bookbinding screws (5mm in diameter and length)</li><li>2mm x 4cm x 40cm foam rubber (for extra padding)</li><li>2mm x 20cm x 20cm foam rubber (for the ears)</li><li>2x 4cm lenses (glass or acrylic). Make sure they are solid half spheres.</li><li>Acrylic paint (black, white and the color of the iris)</li><li>paint brush (small)</li><li>10cm x 10cm mesh (I recommend fly screen)</li><li>4cm x 80cm elastic band</li><li>10cm round elastic band (2mm - 4mm diameter)</li><li>1 roll of duct tape</li><li>~1m² fur of your choice (this is just for the head; paws, tails, etc. will add to this!)</li><li>20m of high strenght yarn (this is just for the head; paws, tails, etc. will add to this!)</li><li>sewing needles (I use one straight and another that I bend slightly)</li><li>exactor knife</li><li>scissors</li><li>water or tea</li></ul>Optionally:<ul><li>fishing wire (for some whiskers)</li><li>flush cutter</li><li>deburring knive</li><li>good quality dog clipper</li><li>your favorite music</li></ul> <h5>A little word of caution:</h5>Filament: You may feel inclined to use a carbon fibre or similarly filled filament. DON'T! These types of filaments tend to shed their fillings over time. You will be wearing this directly on your face and you don't want to glass or carbon fibres in your face. The fully assembled head will withstand accidental abuse just fine even without any speciality filament.LEDs and Electronics: You may want to add some flair with LEDs or other electronic gimmicks. That's fine. But do not mount the battery (especially LiPo types) inside the head. In the rare event that they do catch fire, you should be able to remove them from your person as quickly as possible. If they are mounted inside the head, this won't be possible. DO NOT mount them there.Not as important but still relevant:Fur may be expensive and materials like fleece may seem like a good, cheaper alternative. It is not. Fur adds considerable volume to your creation and makes the suit look nice and fluffy. Fleece and similar materials will mimic the look of a hairless cat. If that's your thing, I won't stop you. But keep that in mind if you want to go for a more fluffy suit. <h3>Print Settings</h3> If printed accordingly to the print settings down below you should easily be able to print your own fursuit head base (including eyelids, teeth, gums and the tongue) in roughly a day.<h5>General:</h5><ul><li>Set the number of wall perimeters to 4.</li><li>Set the top and bottom perimeters to at least 5 and 4, respectively.</li><li>If possible, set the fill angle to 0° instead of the default value of 45° (so that the top and bottom layer lines are horizontal/vertical instead of diagonal).</li><li>Switch off the supports. They should not be necessary when printing in PETG. However, less stiff materials may give different results.</li><li>Additionally: Consider the colors you want to end up with. The head and jaw should be printed in the same colors as the gums. Booth the eyelids and nose will still be visible after furring.</li></ul><h5>Head & Jaw:</h5><ul><li>Make sure that your printer is able to handle bridging and overhangs well.</li><li>Since the contact area with the print bed is very narrow, a brim of at least a few millimeters is recommended.</li><li>If possible, align the parts so that your part cooling fan blows into the inside of the head part and underneath the jaw.</li><li>If necessary, switch on the "Detect bridging perimeter" function. (To check, pay attention to the headband slots on the head).</li><li>Watch your first print carefully.</li><li>And don't forget to drink some water.</li></ul><h5>Nose, Teeth, Tongue, Gums & Eyelids</h5><ul><li>Print as fine as possible. A layer height of 0.1 mm or less is recommended.</li><li>Strong cooling may be required for the teeth.</li><li>If possible, do not add a brim.</li><li>Print the teeth last and don't mix them up! If possible keep them on the bed until assembly.</li></ul> <h3>Assembly</h3> TL;DR: Test if the head fits at all first. If it does, add glue where the parts meet. The long version:The head is provided with built-in support structures and may be printed with a brim. Simply remove those. I suggest a flush cutter, but a exactor knife or even bending them back and forth may also do the trick. Clean up the remaining supports by running the knife or the flush cutter over them one more time.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/93fb1d29-6a5d-4e62-ab08-8d0e2a183ee5/head_2.jpg#%7B%22uuid%22%3A%22ff650c72-0e73-4b49-b88d-9cc3369c813d%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Test the fit before proceeding! Simply connect the jaw and head parts using the bookbinding screws by inserting them into the hinge (marked green) and holding the head against your face. To conceal the human forehead, this head should be worn at an angle of about 25° to 30°.  The head should rest against your forehead and chin and you should be able to see through the tear ducts. Your chin does not have to fit inside the jaw. It just needs to rest against it.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/3bc69b02-d5ab-497b-8bd4-12bf4034eeaa/complete_just_head_marked.jpg#%7B%22uuid%22%3A%22fc2f1fd1-8cab-4745-a07e-0b37d6abf517%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>If the head seems to fit according to the image above, you can proceed by removing the bookbinding screws again and assembling the mouth parts.Arrange the gums, tongue and teeth in front of you, as shown. The teeth should still be approximately as they were on the print bed.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/6e973c09-8663-444e-abda-c36db912b787/gums_1.jpg#%7B%22uuid%22%3A%229f68b186-70a2-40d0-ac31-1e713668b5fa%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>The teeth should now be arranged into two double rows. The two left rows fit the upper gums, (to your left) and the right rows are for the lower gum (on the right).<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/8e40b06d-748f-4722-ac23-a201043f25e9/gums_3.jpg#%7B%22uuid%22%3A%22a01591f8-64fa-4639-92cd-5891ea063ee7%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Now, add some plastic glue to the pre made holes on the gums, shown here in yellow:<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/d108b1d5-698c-4cd0-9784-d2c6b66c017c/gums_2.jpg#%7B%22uuid%22%3A%22e4a5607b-8ccb-4736-a4e0-3706d181d8b6%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>You need to insert each tooth separately. Try to have them aligned as shown, but do not worry too much about their rotation. Their base is made to be slightly oval, automatically aligning them properly when inserted. The end result should look similar to this:<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/77ee8dc5-1e14-4766-a980-4d59d5476224/gums_4.jpg#%7B%22uuid%22%3A%22efadd663-c8fa-44bd-b21f-43a76daf76e4%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>This completes the upper gums. Set them aside for now. The lower gums still need the tongue to be installed. To do so, apply some glue to the inside perimeter of the lower gums (marked yellow).<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/4002cfa5-002b-4b85-82ca-b759b48d0a11/gums_5.jpg#%7B%22uuid%22%3A%2289132289-fd59-43e7-91d5-be48a4037a54%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>And insert the tongue from the top. This step might be a little easier if you can lay the parts on a flat surface (mind the glue tho', you don't want to stick the gums to your table).<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/387db157-cd3d-4d1c-bd6c-38e3c070e09b/gums_6.jpg#%7B%22uuid%22%3A%2263bc22b1-8e40-46ab-b670-a361338535ba%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Apply light pressure to the point shown:<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/aad9019c-0a7b-4a50-bb31-ee7e8b6fa70b/gums_7.jpg#%7B%22uuid%22%3A%22b4e5ae45-29aa-42c7-9b11-c48468d8963c%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>This completes the lower gums. Set them aside for now. While the glue hardens you can continue by gluing the nose to the head. For this simply add glue to it's cut-out.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/07204ece-81a1-493b-b481-6bfba82d810d/head_4_nose.jpg#%7B%22uuid%22%3A%22e3f21956-cf94-437f-9234-314d4f1263a9%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Align the nose to the slightly hexagonal shape of the snout and apply some pressure until the glue has cured.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/706579dc-9a58-4740-8c03-0f3ad2031379/head_5_nose.jpg#%7B%22uuid%22%3A%22d9b0c677-0095-4981-acf3-d83f2d59441b%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Next, you can attach the eyelids. You'll need to sort the left from the right eyelid. The orientation on the print bed is already the correct one. If you mix them up look for the small triangular tear ducts. They should point slightly above the muzzle when inserted correctly. If you are unsure do a “dry run” without any glue and check if the result looks like the image below:<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/676213dd-9d58-4d64-89f1-5014278a6f4b/head_7_eyelids_check.jpg#%7B%22uuid%22%3A%2299e85875-8adf-4b3d-a3a7-6854ffbb23c2%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Please do only one side at a time so that the glue does not harden before the second eyelid can be inserted.Locate the small ledge on the side of each eyelids hole inside the head and apply some glue to it.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/0c984b69-41d5-4b88-adf3-424dfcd0d830/head_7_eyelids.jpg#%7B%22uuid%22%3A%225ba39d35-dcce-40ee-96c1-88d3f4f9a3cd%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Also add some glue to the inside perimeter of the eyelids cut-out.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/ba8164d7-d106-475c-beea-365bf1c15e9d/head_8_eyelids.jpg#%7B%22uuid%22%3A%228dae64f1-071f-43b9-adb4-c29bf0f52ed3%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Insert the eyelid from the inside, by rotating it into it's proper position so it rests on the ledge.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/39020ed8-9b5b-4030-85a6-aaaeb556d1d1/head_9_eyelids.jpg#%7B%22uuid%22%3A%22e0df2110-ed32-410d-b29d-c3d6a76c62b4%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>The eyelid should sit perfectly flush with the ledge. If it doesn't rotate it carefully until it does or the space is minimized. If the eyelid doesn't seem to fit you may have mixed them up. Check again and repeat the previous steps.Apply very light pressure to the point pictured, while holding the eyelid in place until the glue sets. This may be a little finicky (sorry).<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/7fbf8f1e-5529-4179-9dd3-d532d389f835/head_10_eyelids.jpg#%7B%22uuid%22%3A%22faa896f8-1a74-433a-b795-e8a350d15de7%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Repeat these steps with the second eyelid as well.You are almost done with the assembly! This is the perfect time to fill up on water or tea.After that, you can proceed with gluing in the upper gums. To do this, take the upper gums (without the tongue) and locate the small protrusions inside the snout and apply some glue to them.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/53e1d19d-48d3-447d-be81-d199171cb941/head_11_gums.jpg#%7B%22uuid%22%3A%2240ffd974-9fdf-44b9-85a8-9d19b7f73c73%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Also apply some glue to the outside perimeter of the upper gums.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/d6bca29a-bd3c-474f-86f1-ad6d0609f956/head_12_gums.jpg#%7B%22uuid%22%3A%22fb8b098e-873d-489e-b88f-48edcb8d5c6f%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Fully insert the gums from the inside of the head, towards the nose.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/8264b8fb-d481-4124-9295-70527e1b2d33/head_13_gums.jpg#%7B%22uuid%22%3A%224ad8e4fd-7246-49fd-8c9d-4d6f8b4e5f09%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Apply light pressure to the point shown until the glue hardens:<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/8933f428-006c-4196-b5c4-6fc2c6f6c179/head_14_gums.jpg#%7B%22uuid%22%3A%2259655df0-03a1-42d9-8067-23095feffcf9%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>This completes the head part assembly.<figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/89641/rich_content/38c7dcbe-0911-4d85-9a19-6aa594122ddc/head_15_complete.jpg#%7B%22uuid%22%3A%22a680bb36-266f-48da-b3ed-d734e02bfdd7%22%2C%22w%22%3A1020%2C%22h%22%3A820%7D"></figure>Next, grab the lower gums (with the tongue) and the jaw part and locate the small ledges inside of the jaw.
