Hi this is a tray for wall mount.
You can use doublesided tape or the two holes on the back for mounting.
The model is quite flexible if you print only one perimeter like I did.
I printed the flat version. for more of a tray-ish outcome print the deep one.
Print Instructions:
I printed it with a extrusion width of 0.8 on my 0.4 nozzle to have a thicker wall.
Put the model upright.
Cheers
