Nitecore Battery Bank Cap

Nitecore battery banks while being the lightest option available, have a unique bug (or a feature if you ask Nitecore) where if the button is pressed down for more than 10 seconds, the battery enters a hibernation mode. Unfortunately, the only way to exit that mode is to plug the battery in for 10+ minutes, which is obviously impossible if you're relying on it as your power source on a trip. So, I made these caps that weight under 2g each out of 3d printed PETG. PETG is a strong and durable plastic with some inherent flex which makes it perfect for a piece like this. They fit snuggly and are easy to remove but will not fall off by accident.  I also am going to try offering these for sale on my website here: https://friesengear.com/product/nitecore-battery-bank-cap/ and my Etsy shop here: https://friesengear.etsy.com/ca/listing/1588166582/nitecore-battery-bank-cap-nb10000carbo
