M3 Wrench-Knob | IMADE3D

A handy little wrench. Works surprisingly well and printed with carbon fibre infused PLA or PETG, last a surprisingly long time. It's quite deep - primarily made for Nylocks - but works for regular M3 nuts as well of course.

(Fusion 360. After import go to Modify > Change Parameters to play with number of notches etc.)

v1.1 update:

• bit shorter overall
