This is a 3D printed 1:1 air choke balun based on a design from W6NBC, which I can't find the original model for, so, I attempted to make my own.
I don't have any testing equipment to make sure it's actually working, so any suggestions are encouraged. That being said, it got the official seal of “it's probably better than nothing” from my radio club.
The PDF I based this off of says that this is good for VHF and higher frequencies.
It prints in two parts. Apply glue, slide them in as seen in the photos, and enjoy.
