Stencil for drawing accurate circles. These can be pricey so here's one with 40, 42, 44, 46, 48 & 50mm holes. 150mm x 120mm
Download and print! Model pictured was printed on an Ultimaker. I used .2mm layers with 100% infill. Stencil is 3mm thick and printed in 7 or 8 layers.
Sand the inside of the circles lightly when done in order to get rid of any bumps or flat spots!
