Made this to hold a flashlight to my multiboard. There are 5 holes for 2x6mm magnets, you will need to stop at the appropriate layer in order to put them in before continuing. I have made an extended version also for a flashlight that needs to be further out.

Details:

Elegoo Rapid PETG

0.6 mm nozzle and layer width

0.2 mm nozzle height (after layer 19 for magnet insert)
