hhI needed some better storage and visibility for my hobby paints, so I made a modular paint holder. Can be used in any combination you need.

Paint bottles up to 35mm

Revell small cans

You will need

• 6900z (10x22x6) bearings. 
• M10 threaded rod
• M10 nut

I've printed them with

•  ABS (ABS is a bit more forgiving as you will have to smack the bearingsin there with a mallet  so a brittle filament might cause it to crack.)
• 0.4mm layer height (0.6mm nozzle)
• 20% lightning infill
• 3 perimeters
• Supports from buildplate.

The  holders will spinn without bearings, can use a washer to reduce the friction but for best spinnage use bearings.

To stabilize the whole thing a M10 threaded rod is used and in the bottom piece there is a M10 nut pocket. 

Surprisingly sturdy standing on the base with 4 sets of both paints and a top. I will be suspending the thing from the ceiling (rail or arm not decided yet).
