Spooky Pumpkin Fountain

prusaprinters

<p>A spooky pumpkin fountain which is entirely 3D printed except for the pump and the ultrasonic mister. The fountain can be printed on the Prusa Mini or printers with a larger build volume. This fountain features both an ultrasonic mister, which will cause mist to run out of the top pumpkin's mouth and a pump which fills the pumpkins. The water then runs into a river delivering it into the main basin's top plate and finally the water flows into the basin. </p><p>Full disclosure I ran out of time to fully print this in time by the time the contest deadline is. Its also my first design for 3d printing so although its working fine for me, so far. I would expect that some parts fit might be a bit off and that post processing will be necessary. One thing that I will do next time time is increase the tolerance for the parts and add inserts so the parts align easier.</p><p>This print requires a significant (1kg +) amount of filament do to the fact that it needs to be quite solid in order to hold water and its also a decent size. The cost with the filament will be a around 60 USD. </p><p>This Print takes quite a bit of time to 3D print.</p><p> </p><p><strong>NOTE:</strong></p><p>If you have a bigger build volume you should be able to scale the print and you will have more space for things like wires and the pump. Just make sure if you scale the print you make sure you have the same scale across all the pieces. </p><p> </p><p>For the parts, I used the below pump and mister. This design assumes the pump uses flexible tubing to transport water.</p><p><a href="https://www.amazon.com/dp/B07SJGKFT7?psc=1&amp;ref=ppx_yo2_dt_b_product_details">https://www.amazon.com/dp/B07SJGKFT7?psc=1&amp;ref=ppx_yo2_dt_b_product_details</a></p><p><a href="https://www.amazon.com/gp/product/B00GX3H0TM/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&amp;psc=1">https://www.amazon.com/gp/product/B00GX3H0TM/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&amp;psc=1</a></p><p>Also, you will need superglue or another type of waterproof glue.</p><p> </p><h4>Print Settings</h4><p>0.2mm Speed, 0.1 would be better but it takes a lot longer</p><p>Minimum perimeter should be set to 6 or higher for parts that need to hold water. You might be able to get away with less but I didn't want to risk it.</p><p>Filament: PETG or another filament that is waterproof.</p><p>Supports are necessary for some parts, I was able to print the Main Basin without supports.</p><p>You will need to print 3 of the Post file, These fit into the main Basin.</p><p> </p><p>For more info on how to make you prints water-tight check out the below articles from Prusa.</p><p><a href="https://help.prusa3d.com/en/article/watertight-prints_112324/">https://help.prusa3d.com/en/article/watertight-prints_112324/</a></p><p><a href="https://blog.prusaprinters.org/watertight-3d-printing-pt1-vases-cups-and-other-open-models_48949/">https://blog.prusaprinters.org/watertight-3d-printing-pt1-vases-cups-and-other-open-models_48949/</a></p><p><a href="https://blog.prusaprinters.org/watertight-3d-printing-part-2_53638/">https://blog.prusaprinters.org/watertight-3d-printing-part-2_53638/</a></p><p> </p><h4>Assembly</h4><p>Basically fit everything together and superglue it down. Their are some parts you do not want to superglue down like the pumpkin lid or the main basin's lid. Additionally, care need to be taken to when gluing things to the basin's lid or you wont be able to remove it later. Also, sanding the surface with a rough grit will make the superglue adhere better. See the more detailed instructions below. To see how every thing sits together take a look at the SpookyPumpkin_FullyAssembled.stl</p><p>Also, these instructions are what I think will work not what I've actually tested. Their also not in any particular order, so do what you think is the best order and if you find a better way to do something please comment so others can have an easier time. It also will help me make designs in the future :). Also, feel free to remix this design. </p><p> </p><h5>Spout</h5><p>Push the spout into the top pumpkin, so that the water will run into the the Rock_WaterFlow. Next put some superglue around the edges, you can move the spout out slightly then push it in so some of the glue gets smooshed in. The big thing here is you want to form a waterproof seal so the water only runs through the spout and not outside through the cracks. </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/ccebed6f-cb94-4c86-a67d-d3e24ad8126d/spout.png#%7B%22uuid%22%3A%222a7aaf27-5252-4afa-9521-5c0e6a638dc3%22%2C%22w%22%3A1640%2C%22h%22%3A1006%7D"/></figure><p> </p><h5>Pump and Mister Placement</h5><p>The pump is placed in the main basin and the mister is placed in the bottom pumpkin. </p><p> </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/f27dc612-a5a6-47fe-bc34-38d9846e1158/pump_mister_placement.png#%7B%22uuid%22%3A%22deff7bac-97c1-41aa-8ebf-ef12661d9465%22%2C%22w%22%3A903%2C%22h%22%3A1058%7D"/></figure><p> </p><h5>Side Rock Tube Super Glue</h5><p>Glue the top of the SideRock_Tube to the top pumpkin. The bottom of Siderock_Tube gets glued to the removable plate that sits on the Basin. Do NOT glue the SideRock to the main Basin</p><p> </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/3b7d98a1-1bd7-436f-9307-eb53e1622308/superglue1.png#%7B%22uuid%22%3A%225b0ab901-4330-4d4d-97e7-5facb21defa0%22%2C%22w%22%3A1067%2C%22h%22%3A1026%7D"/></figure><p> </p><h5>Side Rock Water Flow Super Glue</h5><p>Glue SideRockWaterFlow to the main Basin but not to the removable plate. In theory this and the above step should allow you  to remove the plate if needed, to replace the pump or something. </p><p> </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/027100cd-00ef-42a9-beb0-b7c2514590d9/superglue2.png#%7B%22uuid%22%3A%22e8adc289-e374-4c9c-ac62-23497cbe1791%22%2C%22w%22%3A945%2C%22h%22%3A799%7D"/></figure><p> </p><h5>Wires</h5><p>Depending on the size you print this and the type of power cord you pump uses you may be able to route your wires like below. If the wires do not fit your best option will be to drill a hole somewhere that will not cause issues. Or you can try to snake the power cords out of the lids. This is another thing I want to improve on in the future of this design. </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/55f6b0d1-3b5b-4b46-b18e-198ed35c0032/wire_01.png#%7B%22uuid%22%3A%22102eef69-e22f-4630-b49b-8f190a019d02%22%2C%22w%22%3A1257%2C%22h%22%3A1113%7D"/></figure><p> </p><p> </p><h5>Water Tubing</h5><p>The below image show how the water tube runs from the pump up to the top pumpkin</p><p> </p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/83255/rich_content/b18c5e14-1bad-475c-ab66-247a5a45069e/water_tube_01.png#%7B%22uuid%22%3A%226bac7ea5-79b6-4998-91fb-7cd0cf1ebe1e%22%2C%22w%22%3A1061%2C%22h%22%3A1193%7D"/></figure><p> </p><h5>Other Steps</h5><p>The other steps are mainly just gluing the parts that fit together so I didn't include a breakdown of those. Take a look at the fully assembled stl to see how everything goes together. </p><h5> </h5><h5>Thanks</h5><p>Thanks to the awesome people in the 3D printing community who led me to get into the hobby.</p><p>Thanks to the people at Prusa for making high quality printers and providing a place to build a community.</p><p>Thanks to anyone who tries to print this design, remixes it, or helps others with it. I'm serious it means a lot to me to see my design get 3D printed and to see others improving it.</p><p>Thanks to the people who develop and support <a href="https://www.blender.org/">Blender</a> the software I used to make this design primary and Autodesk for the now defunct <a href="https://www.meshmixer.com/">MeshMixer</a> which helped to solve some issues along the way.</p>
