[TowerTalk] DIY Air Wound Coils

[David Gilbert]

If you have access to a 3D printer, or access to somebody who has a 3D 
printer, here is an easy way to make your own air wound coils like the 
old Air-Dux coils.  The video is pretty clumsy, but you should be able 
to get the general idea.  I recommend clicking on the gear at the lower 
right of the video and setting the playback speed to 2x.  I'm pretty 
slow if I have to think and talk at the same time.  ;)

There is a link for the OpenSCAD (free and easy to use open source 
modeling software) files in the YouTube description, but here it is as well:

The coil would have looked better if I had let the superglue cure on its 
own.  Running water over it to speed up the cure made it sort of bubble 
up and trashed the appearance.
