stackable AL80CU Scuba tank holder

Divers with double or side mount rig are frequently using pulleys, so called miller carts, to carry their tanks. I modelled a holder for AL80CU tanks for my rig. I also enclosed the Fusion 360 files with the parametric design so one can adapt it to the actual size of the tanks. 

don't be alarmed of the big blocks (modifiers) aside of the actual holders. There are modifiers to enforce a higher degree of infill for the bowtie shape piece that could be used to hold two of the holders together. I recommend a 2.5 cm wide belt to fix the tanks to the pulley.

Have fun, dive safe. 

PETG, 5%-15% infill.
