Dewalt XR Battery Case

I designed this for my Dewalt angle grinder. This is the bottom part of the battery case, which may fit 10 pcs. 18650 batteries (standart 4/5/6 A-h capacity) or 15 pcs. (6-9 A-h extended).
I made two complete XR-compatible batteries with 9 A-h capacity using very cheap DIY cases and 3000 mA-h 18650 battery elements from Aliexpress.
This thing is not a remix, this is my fully from-zero-made project. You must keep top case part with PCB and button and battery spacer from DIY set. I use SOLDER and thick wires to connect 18650 elements together, so case would be a little wider, than original model.
Attention! 10 pcs. version is not tested, print it at your own risk!
The project is being worked on, I will optimise some surfaces and fillets, add logo, etc.
