Frame hangers for canvas frames

Little helpers for hanging a canvas frame perfectly.
Screw the straight one on one side of the frame and the angled one on the other. Now you can shift the canvas to the left or right to hang it perfectly in level. Each notch will lower/heighten by ~0.5mm.

The holes are made to take 2x10mm Spax screws.
Each part has a little indicator for the middle so it's easier to measure.

For convenience, I put the .stl's already "upside down", so you can just drop them into your slicer and print easily.
