As per request, you will find pictures of the welding helmet fan, along
with an explanation of the various components in the metalworking
dropbox.

Be mindful, the pictures are a bit larger than anticipated, my bad.

Look for the following files:

Helmet_Fan_Battery_Small_1.jpg
Helmet_Fan_Top_Small_1.jpg
Helmet_Fan_Bottom_Small_1.jpg
Helmet_Fan_Top_Small_2.jpg
Helmet_Fan_Bottom_Small_2.jpg
Helmet_Fan_explanation.txt
