Simple upright tubing base for 2.5" OD tubing. Can be scaled and laid out in any rectangular grid pattern for a connected organization object, or individual squares for a minimal footprint tubular storage device.

Press fits pretty well, but glue can be added for more permanent connection with the tubing.

Dove tails are set for .05mm tolerance which seems to work perfectly for my X1C with a variety of PLA materials. The connections are sturdy, but still able to be disassembled if you want to pack them away.

My main use case is arrow organization, and I put a bit of EVA foam in the bottom of the tubs to deal with arrow tips.

Only additional materials you need is 2.5" OD tubing. I used this stuff, but any 2.5" OD tubing should work fine. I sawed mine down to 18" tubes for my purposes.

It's probably painfully obvious, but I'm not an engineer and mostly been learning CAD through designing little projects for the house. Constructive feedback and requests help me learn, the more the merrier.
