These baseplates replace the stock baseplate and integrate a bushing for use with templates.
I use these for engraving bits which don't have bearings.
It can be hard to see what you are doing with dust extraction so I printed one in Formlabs Creator Super Clear resin and its much easier! FDM works ok, too. Beware the 3/16" offset when printed in FDM has a very narrow bushing wall so go easy.
It is rigid enough at 0.25mm layers and 30% infill.
Fusion project is attached for customizations.
