This is the first version of the adapter I made for using 18V battery PAP A1 on makita cordless tool. So far it works good, but design can be improved.
IMPORTANT NOTE: on the makita side it is important that the central pin is connected to the + battery side, otherwise the tool won't start. Be carefull that by doing this you are bypassing the battery protection on the makita tool.
The objects can be printed in any orientation, but I reccoment to print them vertically
