18650 battery tube enclosure

Edited the original's 18650 models in tinkercad to add room for battery contact wires. Also added + and - labelling. I used little magnets as battery contacts in mine.

I printed mine with MonoPrice black PLA, it was pretty stringy and I had to clean out the hole openings on the bottom with a drill bit as well as scrape out the channel for the wire with a little pick tool. Battery's fit isvery snug with the wire in there!

Added room for contacts, wires, and labelled ends.
