The idea is to hold groups of 18650 batteries securely inside a tube with a little breathing room between the batteries allowing for wires and such. This group of 8 will fit into a 2.5" OD piece of tubing. This is only a prototype.

Further prototypes. You can see how they will be wired together and how they fit into a 3"IPS PVC pipe. The model on the right in the first 2 pics is an earlier prototype. I am cutting away an area for the BMS as well as reducing the amount of plastic to reduce print time. This battery will be a 10S4P setup using NCR18650GA cells yielding a 36V 14Ah battery with a 40A max continuous discharge rate. Total length will be 33cm or a little longer than the length of 5 batteries.
I am designing this using Fusion 360, sending the .stl file to Slic3r 3D and printing on my Prusa i3 MK2 3D printer.

Further model changes...getting closer!
