Universal ESC Protectors for miniquads

thingiverse

I designed many ESC protectors over time but these stand out as my favorites, especially Model A. They are specifically designed for Holybro F3 Metal ESC (the LED variant) but they will also work with almost any ESC 17mm wide (the "NoLed" variant). The design should scale nicely if your ESC is slightly thinner. I also post pictures and videos of my designs on Instagram as madxfpv. If you need a flexible material, TPU or Nylon works well. It's best to print with a 0.4 mm nozzle at most, 0.25 layer height, 40% infill, and 3 wall-line counts (1.2 mm). To install the protector, use two thick tie wraps and hook the printed parts using from at least two from the three sets of openings provided. Insert the tie wrap like in the picture above to have a firm grip (outside->inside->outside). Fasten the tie wrap around both ends. Cut the protector with scissors or a hobby knife to adjust its length. Now you can enjoy the protection your ESC deserves.
