Keychain containers

thingiverse

Hey there, I recently found myself struggling to remember my midday cold and flu meds. So, I took a nut and bolt prototype I've been working on in OnShape and gave it a makeover to include a space for storing my meds and a fixed ring that lets me attach it to a keychain. The ring is positioned in such a way that it works with the layers of the print to be stronger and less likely to break off. I came up with two designs, one featuring a small hole in the center for smaller items, and the other boasting threads cut back and a large hole for little trinkets. I printed this design on my machine, which has relatively tight tolerances (~±250µm), and the threads were made to have a tolerance of ±500µm. If your machine can't quite meet these specs, you can always adjust the "XY Size Compensation" in Slic3r to thin down the model slightly, giving it a bit more wiggle room. Zap out!
