The base is solid polished brass 5"Ø x ½" w/ adhesive neoprene on the bottom. I 3D printed an alignment jig to hold the shaft perfectly vertical while I epoxied it into a hole in the base. Shaft is carbon fiber rod. Shelves are 3d printed PLA, printed & chased threads to accept large SHCS's to support against the carbon shaft. Inserts are standard 8oz deli-style containers, easy to clean/replace.

Plastic inserts are easily removable (and free to replace if you order some mac salad at the deli)

CAD of the actual platforms. The sketch shown was the revolve cut to match the contour of the deli containers. The threads were modeled as a graphical feature only, but if you print them as-is and chase them with a tap they work really well (still subject to the strength of PLA.. but still, I was impressed).
