The file 'Dremel Micro Charger Docking 3D Printer Model' is (stl,f3d) file type, size is 2.1MB.
I did not find anywhere to buy this doking, I hope you can help others. I did it with Fusion 360, I made the file available for modifications, I got the copper contact in an old plug. You can make other material. The internal plug takes it out of an old arduino.
The spring you will have to get or do it, it is relatively simple, it is also possible without the spring, but I do not think it works well.
It's for this Dremel
