Remixed with horizontal support because these tall thin pieces don't stay steady during printing. No supports needed.

This model is not my design, I just added horizontal supports for more stable printing. As long as your printer can bridge you shouldn't need any vertical supports.

I do not like the way the armor modplates look when printed, with the layer lines and other printing artifacts. I modified Bambu's pegboard modplates here, which print much nicer and have the face texture of your build plate
