A model I made for various tablets and phone devices to the wall for charging or use for easy touch screen access.
I personally use a pair for an Ipad Pro and a Samsung S3 tablet. The slide is about 9.5mm across so you can figure if you have a device with a cover, as long as it's thickness is less than that, it should still be able to fit. Since without any covers the devices still have some room.
I usually feed the charging cord through one of the slots when not in use.
Print with model on the side with opening facing up, no supports needed.
Filament: Dikale PLA Black Notes:
Print a pair and adjust on the wall accordingly. Hole for screw is just under 4mm diameter depending on your print layer accuracy.
Opening/slot where tablets and devices slide into is approx: 9.5mm.Total overall model length is just about 75mm.
