Wall mount for painted desk top

My son wanted to use his old painted table top as wall decoration.
For this purpose I designed these holders.

Printed with black PETG.

I used the smaller version so the fixations are optically less dominant.
The first (and larger version) is “hidden” in the 3mf-project file.
I did not print or test the larger models, the smaller version works just fine for me.

Assembly:

[1] Screw the bottom holders to the wall 
     using 4x5mm SPAX screws (or similar)

[2] Insert the table top into the bottom holders

[3] Place the top holders over the top table top corners and attach them to the wall 
      using 2x5mm SPAX screws
