Compact, specific hand tool holders on peg board

<h3>Additional Summary</h3><p>With all the parts shown in the photos, this takes about 35 hours with a 0.8mm nozzle and layer heights of 0.6mm. I originally designed everything to be printed with a 0.4mm nozzle and layer heights of 0.3mm, but that takes over 70 hours of print time. I am still re-designing a few of the parts to be able to print them with thicker layers. This holds 70 different tools. A total of 92 parts printed with 54 of them being unique.</p><p>I have experimented with different materials, fonts, layer heights, and nozzle widths to try to optimize time while keeping a high print quality and resolution.</p><p>These prints require print-in-place objects as well as filament changes within the prints. I do not have the MMU with my Prusa MK3S, but it would be nice to have for some of these parts.</p><p>All individual parts have a perfect tolerance to be locked in so that there is very little movement, but can also be removed if needed.</p><h3>Materials/Additional Objects</h3><p>The black material is EcoTough 2.0 PLA. The white tool holders is a PLA/PHA. The gray tool holders is ColorFabb_XT Co-Polyester. The white text is Formfutura's Silk Gloss PLA. The yellow text is Fillamentum Luminous Yellow PLA. I was unsuccessful at printing the PLA/PHA on the steel PEI sheet, but it printed well on a glass bed.</p><p>Peg Board <a href="https://www.mcmaster.com/pegboards/pegboards-for-workbenches-6/">https://www.mcmaster.com/pegboards/pegboards-for-workbenches-6/</a></p><p>Magnets x56 <a href="https://www.mcmaster.com/5862K156/">https://www.mcmaster.com/5862K156/</a></p><h3>Fonts</h3><p>The font I have found to work best is Franklin Gothic Heavy. This is a uniform bold lettering that I am able to print size 17 font (maybe smaller)(text printed on the bit holders) with a 0.4mm nozzle, with it turning out great.</p><h3>Print-In-Place</h3><p>The bit holders have 14 magnets in them that are printed within the object. I designed the holes for the bits to be very loose, but put individual magnets under each one to hold them down. This way I don't have to worry about the plastic expanding and making the bits too loose. This also creates a secondary way of attaching the holder to the peg board as the bottom has a very strong magnetic force. This is displayed here:</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/4b2c94f6-b378-468f-b10c-84f74e894b96/20210216_140503.jpg#%7B%22uuid%22%3A%22ca3f50ad-178a-4e25-aa4e-a2ab52ea2871%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>Magnets in each hole:</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/f10cfbfe-6b3f-41d1-b9db-027d7a276ff4/20210216_140525.jpg#%7B%22uuid%22%3A%22637dcf83-82e7-4f84-9b39-6e2ea5cc72ff%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>On the second design of these holders, I stopped putting individual magnets under each bit, but instead put 1 bar magnet. This decreased the magnetic force on each bit to a more reasonable level, while also reducing touch time, and cost.</p><p>I have started developing formulas in SolidWorks to modify dimensions of the bit holder based on the amount of bits needed.</p><h3>Attachment to Peg Board</h3><p>I designed the clips on the back of all the rails to be removeable. The clips lock the rail in the x, &nbsp;y, and z-axis. This was done by creating 2 different styles of clips. They can be seen here:</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/c846b604-efe8-462c-86cd-1b6c31c8f4bb/20210216_141102.jpg#%7B%22uuid%22%3A%22e44cffca-0dc2-4f38-ab9a-a20c8557ce1e%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>The upper clips lock the holder in the z-axis and the lower ones lock it in the x and y axis. This makes it very tight to the board with very little movement in any direction, but also can be removed if needed. This means that there are no supports required for any of these pieces.</p><p>I also put four magnets in the back for a little added support to the peg board. I have since removed these magnets as they aren't necessary.</p><h3>Printing the Description Signs</h3><p>There are two different types of signs that are required. Single and two tier. The single ones are fairly straight forward, just need to add a M600 at the layer that the text starts. The two tier signs are a little more involved if you want to do it with just one M600. As seen here, the upper text is sitting a couple layers below the lower text:</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/11c45568-2894-4fe9-9eca-bded7482d352/20210216_142208.jpg#%7B%22uuid%22%3A%224f72a0db-d683-4369-b24e-0d35ccef2e0c%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>PrusaSlicer wants to insert an M600 to change filaments to print the first layer of the upper text, then another M600 to switch back to the black filament, another M600 to finish the upper text. The only work around I found for this is to manually edit the .gcode file to move all the text printing into one section. I can explain further if anyone want to send a message.</p><h3>Ways I Eliminated Needing Supports</h3><p>There are only a couple parts that need supports, and it only totals to be about 1 hour worth of printing. All the tool holder parts are printed separately and are attached to the rails using dove tail designs seen here:</p><p>&nbsp;</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/e2dc6803-5280-4c97-8ccb-0689ba7629dc/20210216_140854.jpg#%7B%22uuid%22%3A%2236fadeee-e3b5-4db8-a5af-c994ec82c8b6%22%2C%22w%22%3A1835%2C%22h%22%3A1835%7D"></figure><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/5e31039d-ad9e-4330-b8ba-4d709c0e96d3/20210219_173655.jpg#%7B%22uuid%22%3A%22a6ef11d7-8d81-4754-aae0-c2c169e27994%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>The back rails, description signs, and clips don't need any supports due to everything being designed at an acceptable overhang angle. There is about a 0.2mm clearance between interlocking parts.</p><h3>Additional Organizing Features</h3><p>I designed the rail dovetails in a pattern/design table so that the spacing between them are easily changed to adapt to the tool widths.</p><p>Text is debossed in the back of the rails to identify what tools attach to what rail. See photo below:</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/b5c778bc-464c-4e1a-999f-f7373b64a96f/20210219_181122.jpg#%7B%22uuid%22%3A%2218650c63-e16f-41b2-b609-0f9e9fd14385%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><p>Since the distance between the dovetails are specific to the tool holder, I started to deboss numbers in between the dovetails on the rail and on the back of the tool holders. This matches the tool holder to the specific spot it belong to. See below. This is still a work in progress.</p><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/5352cb32-cc6a-4cd6-90ef-cfe426685e82/20210219_181431.jpg#%7B%22uuid%22%3A%22185769e3-6f17-446f-8319-89d73b0f31bd%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><figure class="image image_resized" style="width:75%;"><img src="https://media.prusaprinters.org/media/prints/57448/rich_content/5e790fef-040b-4284-8745-0bb444d682f6/20210219_181421.jpg#%7B%22uuid%22%3A%2261d16106-fd61-4ee6-9849-8c3919cb5ae9%22%2C%22w%22%3A1836%2C%22h%22%3A1836%7D"></figure><h3>Additional Information</h3><p>The tool outlines were done by measuring exact tool dimensions with calipers. The files that are uploaded here are specific to the tools they were designed for and won't necessarily work for others. For that reason I have only uploaded a few parts for trial and if anyone wants help making other parts to fit their tools, let me know. I can also share other parts with people if they think it will work for them.</p>
