My Camera screws came loose while flying so the washers went missing and then I lost one of the washers to the VTX board while I was swapping it out with a AXII Micro.
Then I remembered I bought this 3D printer for some reason. So i designed the washers in Fusion360 and printed the little bastard out.
You can print this in any material but i think TPU would be the best.
