Parametric FreeCad Corner radius/fillet and chamfer/bevel router jig with changeable inserts (metric)

This part is designed in FreeCad. You can create jigs for fillets or chamfers (chamfers can have fillets too) within the given range. 

1. Download the font ArialRoundetBold.TTF from somewhere and put it in the same folder as the "router corner template.fcstd" file (it must be named ArialRoundetBold.TTF). 

2. Open the spreasheet to modify the attachment parts.

3. Adjust the clearance so that the base and the attachment fit together as tightly as possible.

4. Export the fillet/chamfer attachment from FreeCAD to .stl or .3mf.
