Bảng Treo Pin (Pin Board)

Important print grid infill at least 30 percent prob 35 to 40 with no top or bottom layers(layer height can be high) attached photos, 3mf included has 45 % infill, not much should need to be changed, you can always use differing infill like hex if you so desire, this is around 7 in by 8 in but you can scale it without any side effects to any size within reason so keep that in mind, I can make edits to the model if you need them. Made these to store pins I had kicking around on the wall. this does need supports to work any type should work but Ive used grid.
