Black round miniature base with magnet slot

All credit goes to @IsaacHoward

Attached is 25, 28, 32, 40, 50 and 60 mm blank miniature bases with a place for a 6mm x 1mm magnet to be placed.

Also attached is the SCAD file if you want to modify for your own magnets.

Want another dimension? Alter the width value of the OpenSCAD file and make your own.

Printed at 0.15mm layer height with 0.25mm nozzle because I was lazy to change it. 
Suggesting 0.3 layer height with 0.4 mm nozzle for speed

I just generated models of bases that fit rounded 6mm x 1mm magnets and added 28 mm sized base.
