I'm getting recursion detected, and I don't see why.
Here's the whole thing.
I can preview if I turn off the calls to Bolt and Antenna.
Either one will give me recursion.

Antenna looks like it's calling Antenna, as noted. Rename the highest
level module Antenna1 and see if that helps. Antenna 1 can call
Antenna, which should not call Antenna at all. Ever... <grin>

Among other things, you appear to define module Antenna() twice.
Unfortunately, OpenSCAD does not warn about such things.

DOH! :) Sometimes you just need another pair of eyes.
Thanks!

Hi!
Others have already pointed out the recursion issue, but there's another issue you need to look at...
you have 1" as 24.5mm while it's supposed to be 25.4mm.
M6 bolts are 6mm thick on the thickest part, from top of thread to top of thread on the other side, or any unthreaded area before the head.
Spacers usually have 6.1 or 6.2mm Inner Diameter (that's just under 1/4", which is 6.35mm) and typically 10mm outer diameter.
Larger ID allows for slop and that's often not desirable.Washers tends to have larger holes, though.

It's not the shaft diameter of the M6 that I need, but rather the outer
"diameter" of a brass M6 Threaded spacer and bolt.
Still got to source those. I need to be able to solder the three parts
together.
In the end, the purpose of all this is to create a printable shell that
goes over the assembly.
Good catch on the barbarian units conversion! Back in my Vivid (pre
POVray) raytracing days, I built a units conversion for a large project
that handled every unit of length I could find, from microns to light
years. Included furlongs.
Current state of project:
