Nintendo Game sleeve

My boys keep leaving their games lying around so I thought it would be helpful to have a couple of slots attached to their devices so they can keep them tidy and not loose them.

I've created two sizes for the two devices we have.

I've printed using XYD-Flex-1, so the holsters are quite tight but it grips quite well. I imagine the cards would fall out if printed with PLA but let me know if you try it.
