ratchet.stl is a one piece ratchet for small Allen wrench keys, and then you print adapters depending on the wrench size. ratchet2.stl has 6 inner blades instead of 4, and they are a bit thicker, try it in case ratchet.stl wears out too fast and no longer locks. One side is used to screw, the other side to unscrew. Here is a video showing both: https://youtu.be/DXt_zggA6sM I printed the ratchet itself at layer 0.2mm, 50% infill, with PLA I tried PETG, works well too. Not sure which is more robust. I tried ABS, didn't work, it would not lock. It might need different adjustments. The adapters should be printed with 100% infill to reduce breaking risk. Ideally they should be printed flat, so that layers are perpendicular to effort, but I hate supports. So I broke a few. This is to be used with small allen key, from 2mm to 5mm like you often use in electronic devices.
