My 3D printer is out of action (plus I don't have my Badgy yet), but here's a first prototype case design, in a wedge style to sit angled on the table, a little "wedgy"... :)

Print this and see how or even IF it fits...??! Let me know any feedback! No idea if the switch or USB are accessible - maybe with a pin!?

Top should print face down, bottom part should print with "back" facing up, both no supports, and 0.15mm layer height or less to pick up the snap fits nice and sharp.

created a quick and easy "frame" style 3D case that hopefully should work. Won't need any support with only a little overhang on the top corner pieces - any sagging will help the corners grip the Badgy. Should be able to squeeze it in, not printed it yet...
