Easy to Print. No Supports needed with PETG, and I printed at 100% infill - just to make sure that it is extra rigid, and the standoffs stay strong. Print one each of the parts except for the button - where you print two of them. It snaps in place, with no tools needed. It is not super easy to remove from the case but can be done with a flat head screwdriver…

Easy access to the USB port and the buttons are pressable.
