Key holder

thingiverse

Keyholder for regular-sized keys. It functions like a Swiss Army knife. At both ends, a bolt passes through where the keys are attached. You can fold them out to unlock the lock and put them back in to make it a compact keyholder. To assemble this product, I used an M5 sleeve nut with an M5 bolt. It is recommended to use Loctite or a similar product so that the bolt will not come loose. The STL file has some issues with previewing, but when it opens in Cura in layer view, the model seems okay. If you have any tips for preventing this problem, I would love to hear them and learn more about modeling.
