Nanoleaf Wallmount

I bought a Nanoleaf from Amazon and mounted it like the instructions told me, with Glue Pads.
After my Panels fell down the first time I added more Pads and Fiber Tape, but it happened again. I guess my wall is to smooth or the glue is old or whatever, but i had enough, I quickly modelled these Brackets and Printed out a few.

The "Basis" goes right onto the wall, The Nanoleaf Panels go around and the "Scheibe" goes on top, now just put a (4mm) Screw or a Nail through the holes and your Panels are bombtight.
