3D model description

I was not too fond of how the B3603 is super exposed, and requires you to have another power source like a DC adapter to power it. As well as the fastening of wires everytime you will want to use it.

So I took 4 18650 battery holders, switch and banana connectors to create a bit more usable PSU from this. You should be able to get up to 12v from this setup, which covers most of my use cases. I mostly use it for 3.3v or 5v projects anyways.

Parts list:
