Box pegs to allow the secure stacking of milk crates horizontally. No support required.

I've identified a couple of different boxes. The measurement below is the space between one of the squares on the side of the crate:

• A: 32.2mm side
• B: 26.5mm side

To stack crates with the top (hole) facing side, use the following:

• AA: box_peg.stl
• BB: box_peg_2.stl
• AB: box_peg_3.stl
