Coil Concept Exploration

The coil shown is just an exploration into generating 3D printed inductive coils with OpenSCAD.

I am publishing this thing collection to illustrate concepts in creating 3D printed magnetics and coils. The effort is primarily intended for single-extruder printers because that is the most widely used type of printer (plus it's what I have).

The first concept involves the use of voids in an otherwise solid shape. If these voids are spiral in nature like a perfectly wound coil of wire th
