My Displate fell off the wall using their stock mounting solution. I still had the magnet included with the plate, but I didn't have a good way to secure it against my textured wall.
I included holes where the magnet sits if you want to try mounting it with a single nail / screw “covered”.
This is the first time I've gone from concept to printed, and it was a super special feeling. Hope this helps someone else!
Depending on how heavy your Displate is, you might want to use more than the 2 nails I used in the picture.
To reduce the number of holes you'll need to place into your wall, you can try turning the plate 45° (so it looks like a diamond), and use a single hole. (I have not tested this, just a thought).
