My first design with Fusion360. Using 4 neodym magnets (8mm diameter, 3mm thick) to make the top snapping into place. There are two different versions of the case. One with magnets visible so they can be inserted after print. Maybe they have to be glued in, I never made this one. The other one has hidden magnets that needs to pause the print to insert the magnets. I simply checked the layers in Cura and paused by hand. Feel free to edit the gcode to pause at height needed. Make sure you insert the top magnets in the correct direction! Other wise your top will never snap in as it's very unlikely you get the magnets out again without cracking or damaging the top.
