This is a simple plug to fill the hole left after removing the rear wiper blade on an EK chassis civic.
Probably compatible with other 6th gen Civic, but I don't know for sure.
Print in TPU. No supports needed.
It is a very very tight fit so that it's as waterproof as possible.
Been running it for over a year and haven't seen any leak / infiltration yet.
