I recently built the highly popular POTAPerformer antenna designed by Greg Mihran (KJ6ER), and struggled with keeping the elevated radials off the ground.
I tried Michael's (KB9VBR) solution with three of them and a bongo tie, but I really only had rubber bands or other elastics, and that still resulted in a cumbersome “tripod” for the radials.
So, I set about designing these. They're totally print-in-place, so there is no metal to interfere with the radials or the antenna.
Mine are printed in ABS, but they should be fine in PETG as well. PLA will probably not hold shape in a hot car, but your mileage may vary.
The thread on the bottom is a Multiboard small thread, and I use a Small Swivel Hook (https://thangs.com/designer/Multiboard/3d-model/Small%20Thread%20Swivel%20Hook-1135827) to hang some counterweight from to keep the tripod stable.
