A floating wall mount for the city postcard series of lego.

Designed with posts on top to prevent the lego from sliding off. They have about 1mm of tolerance so there is some slop in the fit, but they do the job of preventing the lego set from sliding off.

Keyhole screw mounts on the back are sized to fit screws with a head diameter between 6-10mm and a thread diameter of up to 5.5mm.

I was able to print without supports at .2mm layer height with the bottom of the mount on the build plate. I printed with 15% infill and 3 walls to provide extra strength for the keyholes, but the lego are pretty light and this was probably overkill. Screws are 86mm apart, but it's easiest to just make a template with some painters tape.
