As described. The stubborn americanos may keep their freedom units for themselves :)
Easy to print, no supports etc.
Request if you need more sizes, made with parameters in Fusion 360 so its no trouble making custom sizes within a reasonable range of 20mm+
Added source file as well.
Best to use several outlines (start outside) to give the router bit proper support, thin walls can be broken by the routers vibration.
Edit
Originally posted files with diameter instead of radius which is a bit misleading since the files are named radius. Changed this and made some dimensions into relative dimensions that scale and added 3 holes in center of radius and directions for marking or screwing down the template. new source file.
50mm size got pretty big for smaller printers so i added some compact versions that reduce the overall size.
