A stackable can rack that is easy to print and assemble.
I would suggest adding some rubber, or something grippy, to the area that touches the can. The racks tend to slide around a bit.
Update! I added strips of rubber to the rack and, as suspected, it makes it far more grippy. It's a bit tedious to cut, glue, and place tiny strips of rubber to it, but definitely worth the effort.
