Disc Center Finder

prusaprinters

<p>I designed this tool to easily find the center of a disc, up to 200mm diameter. The diagonal edge is offset by 0.35mm so that 0.7mm pencil lead should be exactly on center. Simply scribe a line on the disc, rotate the disc roughly 90 degrees, then mark a second line. The intersection of the lines should be at the exact center of the disc. Great accessory for laser engraving coasters etc.</p>
