I took Peter Davis's design and added 6x2 magnet slots on the bottom of the gridfinity base. This design also fits the 3403-20 non hammer drill Milwaukee. Shout out to @WLHSTechEd_1309681, their gridfinity stuff is awesome!
The included .3mf is from Orca slicer for a Bambu X1C using PETG HF, .4 nozzle. I probably went overkill on the amount of walls with 5 and also an alternating wall, 15% cross hatch infill, and I slowed it down a little. Nice and sturdy!
If you would like to do the multiple colors and don't have an AMS of any kind…at a .24 layer height, color switch at layer 41.
Cheers, and happy printing! This is very specific, but the idea is very smart!
The author remixed this model.
All I did was add magnet holes in the base to be able to glue in 6x2mm magnets.
