This is a remix of https://www.printables.com/model/254729-circle-router-jig-for-bosch-gkf-12v-8 Take a look there for more details.
I have a 300x300 format printer and wanted to print the base of the jig in one piece. So i merged the corresponding models to one.
Also i only had a 20 mm screw at hand, so i also remixed the knob and lowered the nut trap to use shorter screws.
Supports are needed.
