I needed a simple touch sensor case. I probably over-engineered it a bit, but I really wanted most of the “touchable” surfaces to be printed on the bed so they had a nice finish to them. I also knew that I would be using Dupont connectors on the terminals so I wanted something to “lock” them in place so they could not be pulled out. It had to go together without tools or hardware and be easy to print several at a time.This is what I came up with. Try as I might to avoid using support material, I did end up with a design that requires a tiny amount of support on one part. Printing InstructionsSome of the snap-fit geometry is quite small, so make sure your printer is tuned, your filament is dry, and you are printing with a small layer of height I recommend 0.10mm.I would also recommend using PETG rather than PLA since there will be some flexing to get the parts to snap together.I printed 9 of these in Purasment PETG at 0.10mm , and they all came out nearly perfect.The case top and cable
