Battery Adapter for Bosch
Description
This is for all of you which have an old 12V/14.4V Bosch drill with dead NiMh batteries and want to use your Li-ion batteries from your new 12V Bosch Professional Tool This should fit the green as well as the blue Drills. I tested it with my PSR 14,4-2 There is some room in the model to place a undervoltge protection circuit. If you don't use a protection circuit for the battery please be carefull not to discharge your battery too much since the Bosch professional Batteries have no internal protection. Printing: I printed the "bottom main" part with supports. Be carefull,when removing the support material, to not break your part, as i did. all other parts printed nicely without support.
