Tablet wall hanger can be connected with screws.

Print it twice, mirror one part, it is symmetrical.

made in 2 part so it will fit for every tablet size.

the pen holder may need some sending to fit it all the way down (Samsung s-pen).

2 different angels for the pen:

an angel outside the wall so it easier to reach and don't interfere with charging cable if charging port is on that side
straight alongside the tablet for smaller footprint.

fit tablet with a basic case (the more simple and elegant ones not the rigid ones).

Solidworks files attached for redesign to other tablets.

designed for Tab s7 (plus) it should fit to all the Samsung ones.

25% and up should be fine but feel good with 100%
