Armattan Chameleon ESC Protector

These ESC protectors will fit over the arm. Other ESC protector I made is mounted on top of the arm. That one can also be found on Thingiverse, but this one is my favorite.

Inner size is 20 mm. So bigger ESC's will fit in.

Benefit is that you can strap the protector down very well with a ty-rap.

P.S. I use 2 mm ty-raps. 2.5 mm ty-raps can also be used but are less flexible.
The 2 mm fit very well. I bought them at banggood. Search for Suleve 2.0x100mm black cable ties.
