click-on corners for tablet wall mount

Hello all

This is a design for click-on corners for a Samsung Galaxy Tab A7, but it will probably fir many tablets. The main idea was to create a design where you can screw to bottom parts to the wall, and click-on the top part.

I had to print it with 100% infill, otherwise the tabs would just break off, but it's only 3 grams per set, so that's acceptable.
