Stackable Base

The idea here was to help alleviate the issue of building the rack too tall and it becoming wobbly if you place these throughout the stack it should help with the rigidity of the rack. I printed it with no supports flat on the bed with a brim at 20 percent infill with tree supports for the holes and at a .3 layer height. I haven't built a stack with it yet but it should work.
