Quick Release Keychain With Magnets!

prusaprinters

This is a quick-release detachable keychain that I designed to fit a need I had. I wanted to be able to remove just my work keyfob and carry it instead of my whole keychain. There are products that exist for this obviously, but I wanted to design something better. This model uses 2 - 8mm x 3mm neodymium magnets that are embedded into each part and keeps the 2 halves held securely together, but also easy enough to slide apart when needed. The .3mf file I added has a pause at layer 99, in which you insert the 2 magnets and then resume the print. I designed it to print at a .12mm layer height, but also provided the .stl in case you wanted to change some of the settings. I recommend a fine (.12mm) layer height with 3 walls and a 20% gyroid infill for strength. Here's a link to the magnets that you can get locally at Home Depot in a 10 pack, or you can get 50 of them for about $6 using Amazon
