I created this radius gauge set to assist with creating other projects. I will likely expand the sizes available in the future. This set feature both imperial and metric radii. The gauges I printed at .1mm resolution, but that might be overkill. The holder prints just fine at .2mm resolution. A sharpie works great to give the embossed numbers a little contrast.

STL files were exported in inches, so you may have to convert them if importing them in metric, or scale it up by 25.4x.
