Swiss knife keychain

thingiverse

Swiss knife styled keychain. With this design, you'll need two bolts (M5x20mm), two nuts (M5), and several washers (D5) and toric joints (D5). Those last are optional but make it easier to move the keys. Once printed, take the bottom part with hexagonal holes and insert the nuts into them. Then, take the other part and insert the bolts into the holes. If necessary, heat a little bit to adjust them in the plastic parts. Insert the keys, separating them with toric joints as needed. Fill the rest of the bolt with washers. Finally, use a screwdriver to join both parts together securely.
