Ever needed to draw accurate 60, 50, 40, 30, 25, 20, 15 mm diameter circles but you've misplaced your compass? If so you've come to the right place!

This stencil allows you to draw those diameters. The actual holes in the .stl are bigger by a certain offset to provide clearance for the width of the pen tip. I recommend using the 0.4mm offset version since that worked for me, but I also provided the versions 0.2, 0.3, 0.5 and 0.6mm if anyone wants to use that.

Overall dimensions are 90x190x2.1mm

Printing:

This was designed to use the "0.30mm Draft" profile in Prusaslicer with 3 perimeters. I also recommend setting the seam position to random to avoid a seam in the print that would translate into a small bump in the drawn circles.

Have fun printing and drawing circles!
