UPDATE 3/23/18: Check out this remix on Thingiverse: https://www.thingiverse.com/thing:2839128 This is a completely reworked version of the original design, and I've added a PiZero sidecar to it. I'm not responsible for any issues that may arise from printing this model. All credit goes to feenix82 for his brilliant ideas on layout, cable management, measurements, etc. I remixed this project because my printer or settings were having trouble with the venting. While making changes, I increased the wall height in hopes of creating a flat cover instead of one with walls. I also added uprights to the side tabs and some pretty filleting that might be regrettable. I'll post the source files soon, which I had to create from scratch by importing the mesh, tracing it for measurements and layout, then re-scaling it after discovering a scaling issue. The cable management was redone with patterns because doing it manually would have taken too long. The vents were also completed manually, and I got a bit OCD about symmetry. UPDATE: Several little tweaks have been made to improve the design: * A 40mm side fan has been added * Some fillets have been added to the cable management for strength * The depth of the cover holes was reduced from 50mm to something more reasonable * The posts for the main board were raised by 5mm to help with clearance issues for the power input on the main board * Microscopic gaps between the top parts of the cable management loops have been fixed * The side walls were raised to a total height of 51mm, which should clear the heat sinks on the external mosfets A version 1 is still included in case someone wants the old design. Edit: Version 2 had an error in the port holes. When I raised the main board, I didn't raise the USB and SD card openings. UPDATE 020518: Some issues arose with printing, which I think was a combination of print settings and suspect PLA. The problems were with the circuit board posts, which were being made in a flimsy way. This is because when it's sliced, it will do one layer of the wall for each post then return for another layer. To fix this, I linked some posts together to try to force it to do what I want. Note about cable management: If you send the supports overhang to 88*, it spans the gaps successfully without supports. This makes cracking out the supports much easier. UPDATE 021118: Lots of trouble arose with the cable loops, so I modified the drawing to lose the loops and add holes instead. There is also a bracket that will click into these holes. My thought was that printing these later would speed up the print, reduce retractions, and allow me to print them horizontally rather than vertically, making them stronger. I'll be working on the top cover soon, but wanted to get to a proper test print first because the box is deeper, so the cover can be made simply flat. This should make printing easier, and I won't need to add a fan for the front since there's already one on the side. UPDATE 021318: Successfully printed! Very pleased with the outcome. The cable clips glued in with CA glue very nicely, and there's plenty of room for cables. Will post a cover soon. Print the cover face up with supports. Use "cover1" if you have trouble printing small holes.
