ipad 8 wall mount

After spending hours and hours looking for a simple wall mount to get my ipad 8 on the wall i decided to build my own one. There a some mounts to buy but i don´t want to spend 200€+. I made two versions. One is just the mount, the second one is with a hole to install a 12mm switch (for door opener) like this one:

Distance of wall screws is 275mm by 153mm.

To get a nice finish i would prefer to paint it 2 or 3 times and end with clear varnish.
Have fun!!!!
