deeper cut in the cap
and side groove to help as a visual cue with cap orientation
-----
I just needed something quick, it's not perfect (installing the blade isn't super easy, and not easy to swap blade, so kinda of a one piece one blade thing), but otherwise works.
Easy to print, no print support
Uses a single heat inserts M3, 5 or 4.6 Outer diameter and 3 or 4mm long.
and an M3x4 screw.
Cap is held by friction, two raised bump in the cap pressing against the blade on each side, kinda tight but better that way.
STEP file is there if you want to play with it.
The author marked this model as their own original creation.
