Hello - this is my first upload project!!!

A little history of creation - I bought myself a drill, when it arrived it turned out that there was no battery or charger. I thought for a while that I hadn't read the letters about this purchase - I wasn't upset))) I started looking for the battery itself to print - I found the perfect one here. The problem is that I don't have the electronics from the battery - I went to Aliexpress and found a case with electronics there for 5 dollars. I was happy and immediately ordered two pieces. Then I started looking for a charger and was again a little upset - the price is about 100 dollars with delivery. I have a standard 12.6 volt charger - I asked the engineer if I could charge it like this using only two contacts - they told me that I could. And I started looking for a project that uses a battery as a USB charger for a phone and decided to finish this project so that I could charge the battery itself.

I am attaching Gcode this is for Creality version 3 se - already prepared for printing

also STL sources

I designed the bottom for this device

the point is to screw the bottom to the common one and pull the charging wire out through the hole

In the photo you can see that a large part is worn out - I'm trying to bring it to perfect condition with sandpaper )))
