Summary

I designed a handle for hex bits that features a visible thread pattern. This is particularly useful for anyone like me who needs clear indicators before undoing a nozzle on a printer, especially since the "lefty-loosey, righty-tighty" rule can be confusing when working upside down.

There are four versions of the handle: two designed for shallow hex shafts and two for longer hex shafts. If you prefer a tighter fit, you can print the handle at a lower percentage than 100%. However, on my printer and with my settings, the handle fits perfectly as is.
