Black&Decker pole extension 20V tools

My cedar hedge was too tall.. and my Black&Decker trimmer too short. So, I extended it. Electric trigger still works.

You will need:

-aluminum pole. (I used 21.2mm OD pole. I can create STL with other OD size if needed)
-electrical connectors that fits. I made them myself but you can buy some at the store
-Wires: At least 12gauge
-35mm M4 screw with nut

Instructions:

1-Insert the male printed adapter on the pole. It first tight and I had to smack it on the ground untit it reaches the bottom of the adapter.
2-solder your 2 wires on the 2 female electric connectors, and Insert your 2 female connectors in the 2 holes of the male adapter. the Then you have to make sure the wire is about 2-3cm longer than the aluminum pole.
3-insert the male printed adapter on the pole
4-Connect the 2 male electric connectors to the battery side of the trimmer.(first identify your wires for + and -)
5-screw the adapter on the B&D battery side
6-screw on the trimmer head on the male adapter.
7-align the tool and the battery side, then mark the holes with a punch on each side of the aluminum pole.
8-drill through the poles (you might want to remove the wires so you dont drill them) with a drill bit that is is bit bigger than the m4 screw)
9-assemble again and enjoy trimming
