Multiboard can hex holder

I sanded the top off a couple of Monster cans and used them as storage but I wanted them attached to my Multiboard, so this is what I came up with. Added the .3mf also to show how I painted the supports. I found that the bottom part of the hex grid warps if directly on the plate, so use either supports or a raft.

Any suggestions welcome!

PS: snugly fits European 500ml/330ml cans
