Removable magnet wall holder for 45x32cm photo printed on metal sheet by displate.com

Motivation

For Christmas I got a special present from my son:
A 45x32cm photo printed on metal sheet by displate.com
For mounting this poster, a 80x80mm magnet needs to be glued to the wall.
The magnet then can hold the metal sheet paster by magnetic force.

But:
[A] This doesn't work for structured wallpaper.
[B] I want to do some renovations later and the wall needs to be painted.
Removing the magnet will leave marks on the wall and for the next mounting I very likely need a new magnet.

Solution:
I designed a small magnet holder where the magnet is glued onto.
The holder is then fixed to the wall with thumbnails.
This way it can be removed later and repositioned, whenever necessary.
Besides the tiny holes of the thumbnails, the wall is untouched and wallpaper will not be damaged.

Print

Printed with Sunlu PETG (White) -> colour does not mattter as the part will be hidden by the poster
