Pin Vise

thingiverse

This is a precision pin vise for securely gripping tools roughly the length of a toothpick. I utilize it to hold Dremel bits by hand, rather than integrating them directly into the Dremel tool. The design's tolerances are quite exacting; when I created the model, I chose to maintain the insert at its original 100% scale while increasing the holder to 105% and the cap to 110%, which still yielded a fairly snug fit.
