If you own a laser engraver/cutter you know how hard it can be to position, for instance, your Rotary Adapter perfectly. I know you can buy this stuff but why bother if you also own a 3D printer? So I designed this simple squaring tool that can also be printed on smaller printers like the Prusa MK3 (use Squaring_Triangle_Small) and other comparable sized printers. Hope you guys like it!

Printing notes:
- Material: PLA, PETG, ABS, ASA, etc.
- Supports: NO
- Brim: NO
- Infill: 20% and up
- Resolution/layer height: 0.2

PS I've included the step (STP) files in case you want to fiddle around with it and/or change/improve it to your personal needs.
