Pi Bumper

thingiverse

Human: I've come up with a simple solution to the issue of joining two parts for my Pi Bumper project. The problem is that other designs I've downloaded have struggled with this step, so I came up with an easy fix using 3mm filament as fasteners. I made the holes oversized, but it was still necessary to drill them out with a 3mm drill bit. The design works well, but keep in mind that there isn't enough room for a standard header if you're connecting to a breadboard. Maybe I'll try modifying it later. Print Settings: Printer Brand: LulzBot Printer: TAZ 4 Rafts: No Supports: No Resolution: .2mm using the Lulzbot Cura quickprint Infill: 20% Notes: First time using the Cura slicer, I normally use Simplify3D. I'm very pleased with the outcome. Post-Printing: Drill out the fixing holes to 3mm Use a short length of 3mm filament to assemble The Pi board mounting holes are drilled to 2.5mm so they will need drilling as well. How I Designed This: OnShape After taking a break from designing, I returned to OnShape for this project. OnShape is a browser-based design tool that seems pretty comprehensive. It has a free tier with no restrictions on the number of public designs you can create, plus 10 private designs. The design is available at https://cad.onshape.com/documents/f45f3df28d995e9ba569d82f/w/3c3f48a18c8b0739db8bce84/e/b215a7bbb15c866eeec93289 and can be copied by any OnShape member.
