65W/100W Powerbank Case 21700 4S2P

I am writing the description with the help of a translator, so do not judge strictly if there is something wrong in the description (my native language is Russian). I don't know English well.

This is a remix of this model, the person published the source code, but I cannot specify it as a remix, because the license for its publication pages does not allow. 
 

Because of my work here, I reduced the height and moved the screen to another location. 

• I took the payment on Aliexpress
• Cells 21700 8 pieces Russian-made

I transferred the screen simply by soldering it to the wires, it fits tightly into the seat in the case, so I didn't come up with an additional fixation for it. I also publish it .step file if you want to modify something.
