This was designed to replace the hinged doors for the cartridge slot covers on the SuperCom Partner. The hinges become weak over time due to age and break and this is a replacement. It is worth noting the design is flipped for each side so you'l need to double check if you have the model flipped the right way before printing. This is especially important because if you are using a textured plate you will get a similar texture to the devices OEM housing. I've printed this in PLA but would imagine it should work fine on PETG and ABS as well.
