About this 3D model

Slamming that SD card into the slot on your Prusa over & over might feel good, but the tinfoil cage that the card "bottoms out" on can bend if you cycle it often & hard enough. This means that you'll have to carefully coax the card into the correct position so it connects with the pins on the PCB, which is slow & annoying. This "fob" fits over the non-business end of the SD card, & when it hits the side of the control housing, it aligns the card's contacts with the pins on the PCB. This means you can slam that thing in all day long without damaging the metal stop. Use the fob. Protect your printer, & protect yourself.
