A shelf I designed to hold some of my figurines. To mount, I poked some holes in the back and hung them on some nails, with some adhesive squares helping hold them flush against the wall.
Added by request: models with holes already built in for hanging on nails!
Added also: models that should now correctly be sized in your printing software, instead of having to adjust the size yourself
The D-pad pieces will need a bit of sanding so that the dovetail joints fit together well.
