Harbor Freight Hercules Battery 12V 20V Adapter

Remix(es) of an adapter from c4krauss on Thingiverse.

I liked how super simple his 20V adapter was. I modified the wire clips to hold the connectors that I had on hand, and hold them in a bit better. Also took some material off the wire clips so the screw heads just aren't as recessed in (made them flush instead of recessed in, at least for the screws I had).

Made an overall shortened version that works with the 12V batteries (which is what I was originally looking for).

Embeded “12V” and “20V” into the adapters.

Please note that the 12V version is ever so slightly not as thick (tall), so the wire clip needs to be printed to go with the corresponding main body you're wanting (they'll screw together just fine, but the thickness is going to be slightly off between the two).

It helps to clear the thru holes in the wire clip with a 1/8 drill bit, lets the screws pass through easier.

Uses standard male spade crimp on wire connectors and bolts together using 3mm X 8mm screws.

Please be aware when using these that you're bypassing any and all safeties that are build into the tools! I would HIGHLY suggest an inline fuse on your wiring.
