Grant, after seeing several neat coil form designs in the style of Air
Dux, I've been wondering if a precisely shaped groove might hold the
wire reliably without glue. I imagine it snapping into place with a
satisfying sound. I suppose this would work well only for a single
wire gauge.

People do this all the time for tesla coils. There's a couple
techniques. One is to drill holes in a strip, then saw the plastic
strip down off center from the holes; that leaves a hole that has a sort
of lip on it.. The other is to cut slots that are *slightly* undersize
and rely on the plastic and wire deforming. Another is to drill holes,
then make saw cuts (or mill a slot) into the hole.
