20700 Battery End Cap

This is a minimalist end cap for 20700 Batteries.

Print 1 and the snug fit should keep your positive connection covered.

Print 2, and connect them with a piece of filament between them to provide a safer method of transporting your battery! Use a longer piece, and you can put the caps on and twist for a tighter fit.

Everyone's 3D printer has different tolerances, and found that what works for me may be different on another machine, so you can print a small piece and try different Filament hole diameters before committing to an entire job.
