A set of wire guides suitable for up to 3.5mm overall diameter wires for making wire based moxon or cobweb style antennas.
These clamp on rather than screw through the tubing so do not weaken the fibreglass spreaders. Also the wires pass freely through the guides so can equalise the tension in the loop across all spreaders.
They just need an M3x12 pan head screw and ideally an M3 nyloc to be able to nip up securely but not crush.
Could be used for any other similar project.
Sizes from 7mm internal diameter to 25mm internal diameter in 1mm steps. Each shoud cover about ±½mm from design size.
Recommended print as shown (yellow image), in PETG, and with many walls to make essentially 100% walls. I print with no supports.
