I like the original idea of the small single piece ratchet which can be a real lifesaver in small and narrow environments. But due to it's design you can't apply pressure to your screw as the bits will slip through the ratchet, i.e. when using PH (phillips), PZ (pozidriv) or even slot bits. So I modified the ratchet that the bits are held in place if you push against your screws. So now we have two ratchets, one for screwing in and the other one for screwing out. I also removed the keyring hole and the arrow for the direction as the type (open/close) is printed on the side of the ratchet. PLA or PETG with 15% infill and 0.15mm layer height works well for me.
