After removing the protective film, it is hardly possible to transport the cans with the original cardboard, so I designed an alternative myself.
The 12 can version is only one part.
I had to halve the version for 24 cans in the middle due to the lack of printer size. Therefore, the tray must be printed twice and one set of connectors. The connectors are a snug fit, you don't necessarily need glue. The 24 Can version is not the sturdiest but is much better than the cardboard.
