A robust protector for 900MHz dipole antennas, similar to an Immortal T. Great for a TBS Crossfire or FrSky R9 receiver.
The arms hook into the center pieces which clam shell together. Zip ties up to 5mm can be used to hold the center together, though it could also be glued.
Immortal L is currently untested. I only worry about the zipties holding it together. If you glue it, it will definitely be fine.
90A+ Shore TPU
Could be printed in any material, but TPU is the most durable, and is recommended.
Optimized for a 0.4mm nozzle.
The arms should be printed with supports. Though the arms can be printed vertically without supports, but in my test print, it failed because the TPU wobbled too much during the print.
The center pieces don't need supports.
