Vase Mode Cassette Organizers

I came up with this design a while back as a way to print lots of storage for cassettes without going insane waiting on hundreds of long prints. I print these with an 0.8 nozzle and 2 bottom layers. It takes about 4 hours for the biggest one, and they come out nice and sturdy. Your mileage may vary for smaller nozzles, let me know what you find out!

Note: The pockets on the side should face upwards when slicing.

Adding sticky rubber feet on the bottom is not required but makes them much easier to use.
