I designed this to hold Lego models to the wall, it comes in a 1, 2, or 3 brick version. Designed to hold a on the axel or other cross-beam under the model. I recommend command strips for the wall mount, but I did include holes if you want to go deeper. PTEG recommended to fight weight creep, but I'd bet PLA would work for a very long time.
The Ferrari and F1 car required a 1 brick separation, and the trucks a 3, I assume other things may need 2.
The author marked this model as their own original creation.
