The Air Blower V2 for DeWalt, Makita & Milwaukee 18V-20V batteries

This is the air blower version two that I made for two very specific reasons – to vastly speed up the ignition process in a grill and regain the loss in heat when coal is covered in ash. It works really well and it is so much fun to use it. :)

The blower has inexpensive electronic parts and a speed controller for variable speed to use the blower for other purposes. I designed it for DeWalt 18-20V, Makita LXT 18V, and Milwaukee M18 batteries from power tools.

IMPORTANT! Makita will require you to buy an original spare part to make it work! Part number - 643852-2. More info about it: https://www.thingiverse.com/thing:4459529
Meanwhile, on Dewalt and Milwaukee, you can just use 6.3mm male spade terminals to make contacts.

In each zip file you will get:
-SketchUp file
-STL files (top motor mount, handle, PWM+Switch part, and the adapter for the battery are free, I include them just for convenience).
