This is a Keurig K-Cup holder. It can be stacked to any number. Print any number of carousels and tubes to stack up. Each level holds 10 K-Cups. Use plastic glue to hold everything together except for the carousel which should spin freely, unless you want them fixed.

It has been a couple of years since I started with 3D printing, but I am still a novice because I do not design that often. I can think of many improvements to this design. Any feedback is welcome.

2022-04-01: No real changes, but arranged STLs in the orientation for easier printing for some people. Added STEP file.
