All in one Battery and Tank Holder/charger

thingiverse

This is a compact 18650 battery compartment that's easy to print. Four holes are included for inserting the charger's contacts, allowing the last two batteries to be charged at the same time. Two tank containers are also integrated into the design, each capable of accommodating either a 22mm or 25mm tank, providing a convenient way to fill them up as needed. The model is designed to print without support, except for the two square blocks on the sides that require some extra care. To complete the project, I'll be adding a lower part to hold the battery charger electronics. For those interested in seeing the full print process and test operation, I've included a link to a YouTube video: https://www.youtube.com/watch?v=Y60cqsL0COQ When it comes to connecting the batteries, it's essential to use simple paper clips inserted into the four holes and bent slightly. These should be properly connected to the contacts of the lithium battery charger circuit, not a mobile charger! If you're new to lithium batteries or electronics, I recommend using this project as a convenient stand instead.
