Flipper Zero hard shell case with GPIO cover
A bumper-style protective shell for the Flipper Zero, whose body is 100 x 40 x 25 mm. The shell wraps the back and sides with 1.8 mm walls, leaves the screen, D-pad and back button fully exposed, and has cutouts for the USB-C port, the infrared window on the top edge and the 1-Wire iButton pad. A sliding cover on the top edge protects the 18-pin GPIO header when no module is attached but slides off so a WiFi dev board still plugs in. A pair of 3 mm holes at one end take a lanyard. Print it on its back with a 45 degree chamfer under the lips so no supports are needed.
A shell that fits your own module setup is hard to find as a download. In SpeakCAD you describe it, preview it free in the browser, ask the chat to open the GPIO slot permanently or add a belt clip, and download the STL when it fits.
