Battery Adapter for Bosch by BrainHunter

Last crawled date: 2 years, 10 months ago

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 not when removing the support material to not break your part, as i did.
all other parts printed nicely without support.
