due to limited space behind the printer and unwillingness to use the proprietary screws i made a megentic version where the magnets are actually sitting in the parts and are not attached by duct tape.
I printed with 0.2mm PETG
no supports necessary, just added a small brim
use neodym magnets 10x5mm, cost about 25 cents each, I had laying around
The author remixed this model.
magnet seats and clearance for the screws
