This is an "Immortal-L" configuration holder for Source One v3 frame, but works on any frame. It will hold firm your own antenna configuration in an L-shape. Idea of Immortal-L comes from Mr. Steele, he released a video how to do it on youtube. Check his channel for help on how to do it. Basically he converts the Crossfire nano receiver stock antenna into an L-shape antenna with 2 zipties and some heatshrinks, but I found his method a bit ugly, so I went further and developed this little tiny part that can hold the antenna with less stress. Must print from TPU for flexibility.
Print upside down, double tubes on the heatbed.
