This is the ideal solution to organize your loose 18650 Li-ion battery cells. The holder can hold up to 30 18650 cells.
There are 2 versions included:
-A standard version: "18650 Li-ion battery holder stadard V3.stl"
-A slim version: "18650 Li-ion battery holder slim V2.stl"
Since the cells kept glying out in the original design, I decided to add stop shutes to the end of each track. I kept the loading port on the top of the standard version but it's recommended to load the cells through the bottom like a magazine. On the slim version I removed the top loading port to prevent cells from flying out. The cells can only be loaded through the bottom on the slim version.
Estimated time to print with tree supports is about 24h.
The size of the holder is 74 x 135 x 150mm.
