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: https://shop.pimoroni.com/products/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 possibly two magnets, each with a diameter of 10 mm and a thickness of 2 mm.
I have designed the housing so that 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 with this enclosure.
Please use screws that have a pointed end. These ones work well: https://www.amazon.de/Karbonstahl-selbstschneidende-Maschinenschrauben-Befestigung-Reparaturwerkzeug/dp/B07T5WX7HY
Update 1:
On a second badge I recently ordered, the display was slightly off compared to the first badge. I have therefore designed a new version (V3), which has a larger cutout for the display. Additionally, I reinforced the backside, so that the whole case is now very stable. But the best thing is that this version is compatible with the lanyard from Pimoroni. If this is not used, the gap can be covered by a fitting piece.
Update 2:
As jakjak found out, the lower part jammed a component on current versions of the board. I have adapted the part accordingly (BadgerCase-Bottom-V3.2.stl).
Always make sure that the case doesn't damage any parts on the board and if necessary remove some material from the case with a cutter if it doesn't fit and notify me if you find a mistake. I will then adjust the housing.
