18V LXC Makita USB charger powerbank with QuickCharge QC3

This is USB powerbank made of Makita 18V battery. Compare to Makita made one, this has all the Quick Charge capabilities (not just 5V/1A) and is a bit cheaper - but that was not the point here.

You need QuickCharge, double port board for 12-24V and Makita battery insert.

The USB board can be bought on Aliexpress for 2,6USD (https://www.aliexpress.com/item/4000001793805.html).
It has output power up to 24W (5V/3.4A, 9V/2.5A, 12V/2A, etc.) and
· Support DCP protocol, BC1.2, Apple, Samsung protocol
· Support Huawei Fast Charge Protocol FCP/SCP
· Support Huawei Fast Charge Protocol AFC
· Support Spreadtrum Fast Charge Protocol SFCP
· Support Qualcomm QC2.0 and 3.0
· Support MTK PE1.1/PE2.0

Makita battery insert, you can also buy on Ali - but it's ridiculously expensive there (it's just plastic with three metal inserts) like 9-11USD. I bought mine for less then 2EUR as a spare part (643852-2) for Makita drill - original product.

I've create mine own Makita battery holder model (there is quite a few already here on thingiverse) - because some of them where too lose for my taste, some where to rough after print, and I wanted it for future use with other projects.
Anyway - I've prepared screw holes in battery holder, but they are not to be used for powerbank - just glue those two parts together.

Battery holder (perhaps not the best name ;) ) - requires supports for printing.
