universal & invisible tablet wall mount

I couldn't find an invisible mount for my tablet, so I made my own.

To attach the wall bracket horizontally to the wall, I proceeded as follows:

Variant 1:

1. attach the tablet-holder to the tablet with double-sided adhesive tape
2. slide on the wall bracket
3. attach some double-sided tape to the wall mount
4. align the tablet on the wall, press it and release it
5. mark the drill holes and finally attach the wall bracket, possibly with the additional spacer

Variant 2:

The variant must be printed with support and can be mounted directly on the wall.

Variant 3:

Modification of the sides to create space for 10 mm adhesive tape and for direct mounting on the wall without the spacer.

Maybe I'll make a smaller version for smartphones if someone needs that.
