Circle Center Finding Tool

thingiverse

This is my take on a circle center finder tool for round stock ranging from 1/4" to 7" in diameter. The slot is positioned to offset the width of the marker or pencil tip. I've created two versions - one with a slightly wider slot for general marker use and another with a thinner slot for mechanical pencils with a 0.5mm lead. Three lines crossing at the same point with this tool verify the center of the round stock. To avoid under or over extruding during the print process, it's recommended that you thermally calibrate your filament using these clips: https://www.thingiverse.com/thing:2502677
