Flex coupling for Einhell battery powered angle grinder

This is a replacement for the flex coupling an Einhell TE-AG 18 Li connecting motor to angle gear.
To work properly this part should be printed with elastic filament. I used PLA - also works, but doesn't suppress noise/vibration that much.
Installation is simple: Remove the four screws connecting angle gear housing and grip to the main tool housing, replace coupling with this part.
