Magnetic latch

Printed in PLA at .2mm.  In use (as pictured) to hold polycarb enclosure doors secure when closed.  2 magnets go in frame_mag holder which attaches to 30x30 with one M6 bolt and t-slot nut.  Insert other magnets into handles and attach to doors so that they align with the magnets mounted to the 30x30.  Polycarb in picture is 3.5mm thick and magnetic holding force more than sufficient to hold doors secure .

I'm short one magnet in second picture, there should be another one on the right (alas the perils of working with what you happen to have on hand!)
