BLS-5 battery cover

A cover to protect the contacts of a BLS-5 battery when carrying it in your pocket or camera bag. The cover is designed for a printer with a 0.4 mm nozzle, as all walls have a thickness of 1.2 mm. The layer thickness should be set to 0.16 mm for an optimum printing result. The cover is designed such that the battery doesn't lock in the cover, but doesn't come out by itself. The BLS-5 battery is compatible with BLS-50, PS-BLS5 and PS-BLS50, so the cover should work with those batteries as well.
