A 3D printable case for the Proxmark 3 512k
(Such as those available from the Piswords Aliexpress store)
Print at 0.16mm layer height in your choice of filament. Example in the above image was printed in Siryatech Grey ASA filament.
Standard / normal supports at 30% density seem to work better than tree supports.
Enable ironing on top surfaces for a smoother finish.
2 layer thick (0.32mm) mouse ears have been added to the corners of the lid to assist with bed adhesion. These can be cut and sanded off after printing.
Proxmark3 can be attached to the base with double sided tape to prevent rattling around inside the case and the lid can be attached to base with a couple small dots of super glue along the bottom edge. The case is rather thin, so if removal is needed later at any point just snip the lid off with a pair of filament nippers.
