I print in PETG with 4 wall layers, 0.2mm layers, 40% cubic infill, and no supports.
The part is orientated with the flat side touching the build plate, and the magnet hole facing upwards. This makes the hexagonal print with the corners facing up.
The magnet is then superglued into place.
This was modeled to fit my Ridgid 18V Impact Driver but it can fit other brands. I sell this on my Etsy for people who don't have access to a 3D printer.
