This is a fix for the problem of the Displate Wall-sticker, which does not really stick to a rougher wall. It is basically a tray, in which you can put the magnet, delivered with your plate.
The “Displate close” file is the one in the pictures. It adds basically no additional space between wall and Displate. For this one, you need a 0.12mm / 0.18mm layer height.
The other two are either a spacer, which adds 5mm / 10mm of space between the plate and the wall.
For the nails, they should not be thicker than 2mm and have a head between 2mm and 6mm.
Especially for the 10mm Spacer I would recommend a nail, at least 20 mm long.
For any wishes/proposals, just leave a comment
