SD card holder that adds a little Prusa flair. I recommend that you print this on either end, but not laying down. also works fine with micro SD to SD adapters!
Update 1/7/2022: I have tightened up the opening a bit on all models. There is little to no wiggle room once the SD card is inserted now. The SD card is still removable with a bit of force, but will likely never come out with normal use.
