Drilling Bounding Ring / Drill Stop using M3 screws and heat inserts made with OpenSCAD

Just a remix of a drill stop to limit the drill depth. The prebuild stl-files are for drills with diameters from 2 to 14mm, but you can customize this easily for your needs with OpenSCAD, the file is also attached. You will need the great BOSL2 - library for OpenSCAD ( https://github.com/BelfrySCAD/BOSL2 ). You will also need 3mm screws (i used flathead screws) and heat inserts (i used ruthex RX-M3x5.7) The customizer allows to change the tool height, the drill diameter, with or without printed diameter, clearance of drill diameter and screw holes
