HOTO Precision Screwdriver Bit Adapter

This adapter allows you to use the HOTO double ended bits in regular sized 4mm sockets, they fit normal sockets but loosely because they're just slightly too long to get a good grip.

I used this one from Amazon but most should work, scad file is attached for different radius sockets.

Material: eSUN TPU 95A (or add tolerances in the scad file, otherwise PLA will be too tight)

Infill: Any, I used 30%

Infill Pattern: Any, I used Gyroid

Resolution: Any for TPU or 0.15mm (or finer) for non flexible filaments (set tolerance in the scad file to the resolution you're using if you're not using TPU)
