This was designed as a mod for the "V1" Nanofly which was 1s only that I wanted to run 2s on. This mount may work for the new Nanofly20 2s but I am not positive since I do not own one. I designed the mount to fly my odd shape no name 2s 450 battery which is slightly larger thickness than the average GNB/BetaFPV/Tattu 450 or 550 2s. I have some GNB 2s 550/BetaFPV 2s 450 packs as well and will upload another version for people running those.
UPDATE: 2/3/2024
I am adding a v2 design that is about half the weight, easier to print, and stretches easily fitting 450 to GNB 720mah 2s 100C batteries. This design may look brittle but TPU printed in this axis is very strong, and the stretching can help reduce inertia during an impact.
You will need to print two of the v2 design, no need to mirror.
