Really simple but effective can holder/organizer for a fridge (or other) shelf. I printed in clear PETG on vase mode. Print with one of the sides down standing. Use double sided tape in fridge to help stick to shelf.

There is a left and right side (just mirrored) to combine and enlarge as needed, you can also just flip the print over in slicer to get the same mirror effect. I had to split in half to fit on Prusa Mini. Each half holds 2.5 cans so doesn't really work well if you only print one half. 

Each half takes about 1.5hr to print on default Slicer vase mode settings.
