A simple tool holder loop. Easy to print and easy to mount. Just use regular woodscrews/bolts.

EDIT: I've added the STEP file for easy modification if you'd like a different size loop

Specs:

Loop size (outside): 100x30mm
Loop inside size: 90x20mm
Baseplate: 70x20mm
Hole distance is 30mm

Print instructions

Print using PLA or PETG and 0,2 or 0,3 layer height. No supports necessary.
