This is a universal battery charging dock, to hold all your types of batteries while they charge.
you can turn the knob to close og get a bigger gap to fit your batteries in.
theres a 2.8mm hole in each wall to use a screw if wanted as the connector to the battery.
in my case i used some metal from some soda cans to make the connection.
Im sure some screws look nicer but whit the use of some tin cans you can bend it and glue it to the end walls of the print, and this makes for a more of a spring action when you put the battery in the dock, this makes for a better feel and no need to adjust the screw to take out or in a new battery between charges. ENJOY
0.15mm or lower (in my case)
