Bevel gauge

I needed to cut two pieces of wood at specific angles, but buying a bevel gauge from the hardware store just for those cuts didn’t seem worth it. So, I decided to design and 3D-print my own.

The first version worked fine, but I noticed one small drawback: the angle-locking part stuck out past the body, which made it awkward to position—especially when trying to transfer the angle to a miter saw.

For the second version, I redesigned it with a low-profile knob that doesn’t protrude, so you can flip the gauge either way without interference.

I also made an alternate version with a simple sliding lock that can be raised or lowered to secure the angle.

The stock is 125 mm long, and the blade is 200 mm. You can also add two small magnets 4x2mm (optional) to keep the blade stored in place without locking the tool.

A specific plate with a break for your magnet is included in the GCODE:

Lock adjustment tip:
Keep the lock in the “up” position (flush with the body), then tighten the screw until the blade doesn’t move. Test the lock and fine-tune the screw tension if needed.
