I needed a circle template to use with my stained glass patterns, so what better way to do it than with the 3d printer? The holes are meant for pushpins (the aluminum ones preferably) to be banged into a piece of plywood or MDF. OpenSCAD file included, so if you need a circle some size other than 7.25" inner diameter, you can edit the file yourself. I'm working on being able to have it any number of degrees, and repositioning the holes.I sliced mine with, 100% fill, extruder at 200C, bed temp off for the white PLA.
