Description

PDF

Radius gauges with a fairly useful range of radii to measure, both for half round objects as for 90° corners.

(The 180° gauge isn't labelled because the model file got corrupted in a crash, so I couldn't make changes to it any more.)

I printed these in PLA using the 0.15mm quality setting. No special settings needed. @
