I wanted a case for my 2 extra “normal” and my ethernet Expansion cards for my framework laptop.

The model comes in two parts with cutouts for the cards.

In the closed state they're held together with a total of 8 magnets (round 3mm diameter 2 height). The cards themself stop the lid from being twisted off.

I printed this on my Ultimaker 2+ with a .4mm nozzle.

The magnets were glued in with some ca glue.
