Swiss Army style keychain

thingiverse

Creating a Swiss Army-style keychain, I opted for a slightly larger design. However, I have plans to develop an even more compact version. I'd like to share my process despite the size, in case others are interested. To make this keychain, you will need three 3mm socket cap screws (length dependent on key count), along with nuts sized for nylocks. Washers can replace the spacer or act as a tube in the middle hole for varied spacing. Washers ease key removal and provide snugness, but may be lost if opting for reduced overall thickness.
