Raspberry Pi SD card muzzle

thingiverse

If your Raspberry Pi 2 or B+ has a broken SD card slot (the locking spring occasionally fails to function), don't discard it yet. Create this adapter to hold the SD card in place. The adapter sits on top of the Raspberry Pi, with a block extending below to prevent the SD card from being pushed out. If you're using a frame mount (my photos show a VESA spider mount), I recommend using slightly longer bolts. Attach the Raspberry Pi to the frame with nuts, then loosely attach the adapter. Insert the SD card and finally secure the adapter properly onto the other bolt. Make sure the card is securely held in place before powering up the Raspberry Pi. You can also use this adapter on newer Raspberry Pis to ensure the SD card doesn't become dislodged. Two STL files are included: one with a thin design where the adapter is directly attached to the Raspberry Pi, and another that allows for a nut to be used to hold the Raspberry Pi onto your mount. A SCAD file is also provided if you want to add the code to your own Raspberry Pi mount. The coordinate [0,0,0] represents the midpoint between the mounting holes on the upper face of the PCB. You can print this adapter with any settings that suit you.
