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.
The author marked this model as their own original creation.
