The file '2xCRGR 18650 Power Bank 3D Printer Model' is (stl) file type, size is 1.9MB.
That's the 2x battery version of my original CRGR (https://www.thingiverse.com/thing:2765404)
Everything is the same but it designed for use with 2 18650 batteries
Model is perfect fit for this USB boost converter and even for a bit longer batteries.
Use a spring terminal in the deep end, wire should go in a long groove on the side
Excessive wire can be stuck under a PCB, just make sure that micro USB is fit in it's slot first.
Board I use is "DC-DC Step Up Power Module Boost Converter" from AliExpress
Cost me around 7$ for 5pc
Picture of the module attached so if you want to make this power bank you'll know what to get.
