AA / AAA / C / 18650 battery holder with integrated spring

Works great!

What fillament do i need to use for this pla, tpu?

Great design. printed to recharge aa and aaa with my RC charger and monitor their charge capacity

Paired with this mount " https://www.printables.com/model/574199-thermometer-and-humidity-meter-thermometer-und-feu/comments" now I have a sensor that should last for so much longer than the button cell it would normally run on.

Works good.

Very useful, used in a project to "extract" all the power from anAA battery and power an USB true a converter (reusable emergency power bank)

Perfect, prints perfectly.
Thank you

Good model, I used the C version to make an led light
