Here is a doubled up planetary gear bearing to hold a 24 mm diameter battery mod and 6 15 mm diameter tanks like the Kanger T3S. Overall diameter 100 mm x 40 mm tall.
Created 2 100 mm diameter x 20 mm tall gear bearings (1 with gnu's script for holes in planet and 1 with emmett's original matching parameters). I then imported the stl files into sketchup stacking them on top of each other and did some cleanup and extended holes into non-hole side for more depth. This basically created a doubled up herringbone gear. I'm sure this all could have been accomplished in OpenSCAD, but my skills aren't quite there yet.
Updates:
01/26/2015: Added wider base to allow for holding on edge while spinning the outer ring.
Printed with .2 mm layers, 20% rectilinear infil in Slic3r. Took ~14.5 hours to print.
