18650 battery cap TPU

Print in TPU. Simple solution to cover both ends of an 18650, when carrying it loose in a backpack/toolkit to prevent from shorting on metal objects.

Very lightweight, uses only about 2g of TPU per print. You can carry multiple caps with you in different colors, and mark batteries which need charging after you use them.
