Hi,
I suggest printing the files using PETG even though i printed it in pla and it seems fine. You don't need supports for the print. Use 3 Weinregal-Clipper's to attach one side to another. You might need a brim though. Not sure on how big you can scale this up since I went for nicer design over rigidity. I tested 3 layers of wine in height so far and it is no problem. Please share your prints and if you have any problems printing. My first upload of my own design.
