Just a simple rear mount for a VTX antenna for the CL1 frame by rotor riot. I made this since my frame had no way of mounting the antenna.
I used a cheap TPU and the fit onto the frame is noice and snug. No fear of this sliding up and down the spacers. The hole for the antenna has some wiggle room (8mm) but a washer should suffice if it's too large for you.
This piece is plenty rigid but with some small amount of flex in case of a hard crash.
After a good few crashes it's held up nicely without any sign of damage or wear.
Took 2hrs to print at 50% infill.
