Badger 2040 Enclosure

This is my version of a 3D printable enclosure for the Badger 2040. A hackable, programmable badge with E-Ink® display powered by the Raspberry Pi RP2040. This exceptionally affordable badge is sold by Pimoroni: Badger 2040

The enclosure consists of only two plastic parts which are easily printable without support on any 3D printer.
In addition to the plastic parts, you only need four 2 mm (pointed) screws with a length of 10 mm and optionally two magnets, each with a diameter of 10 mm and a thickness of 2 mm.

All connections are still accessible. Any cables you might want to connect can be routed to the centre of the back of the badge. This way you have one place where all the cables come out. In combination with the magnets, the badge can be used as a display for all kinds of projects. Of course, you can still use the badge as a badge, because the hole for the strap is also there. I especially like the barely visible buttons on the front of the badge.

Glue the buttons onto the tabs. This is not absolutely necessary, but it enlarges the button area so that the buttons may be easier to touch.
