No load. They're just discs/plates with a hole in the middle that the mast goes through and holes near the edges to keep the individual wire elements separated from one another... But I wouldn't be afraid to try PLA for light load-bearing applications. Save the file so you can print again if it breaks. Plastic's cheap, and PLA is recyclable. Some say biodegradable, but that takes a very, very long time... ________________________________ From: Gokhan KORALTURK <gok...@gmail.com> Sent: Friday, September 6, 2024 7:51 AM To: Jeff Greer <gree...@hotmail.com> Cc: BRAZOS VALLEY AMATEUR RADIO CLUB <bvarc@bvarc.org>; mike.williams shopjubilee.com <mike.willi...@shopjubilee.com> Subject: Re: [BVARC] 3d printing for ham radio
Hey Heff, were they carrying any load, if so maybe later I can pick your brain a bit for help then? I'd prefer PLA if I can, simply because it's more environmentally friendly but I could not print anything that would survive being inside a car while holding any sort of weight. MY outside camera mounts were the same even if they are not inside a car. Maybe I'm not doing it right.

Especially here in Texas where it can get severe heat or worse yet very quick changes in temperature. Especially anything contained in a car would break very easily. (Mostly from layers) PETG is very sturdy outdoors but still gets a bit soft if it is for instance right under the windshield in a car, but it survives if it is printed with 100% infill. TPU is usually fine, it get a bit softer than normal under windshield but does not melt and in my experience it survives the cold just fine. I'd add more but I'm down with covid so hope this helps!

I participated in a EFHW Antenna class where we built transformers onto 3D printed substrates. And I have found dipole termination plate models. Beyond that, looking for other ham radio related models and targets. What say you? What experience have you had with outdoor use of PETG, TPU and PLA? Thanks in advance!
