Corner Square for Woodworking

This little helper is often made from aluminium or quickly done with wood. However, I printed a bunch of them to be used with small clamps.

Two sizes: 123x123 mm and 79x123 mm

Print settings:
No fill and no top and bottom layers, only perimeters.
Works best with a 0.4 nozzle and 0.3 mm layer height. 
I’ve printed mine with PLA, but PETG should work fine also.

This corner jig could also help:
