The original plugs that connected the drain tubes to the bottom of the windshield started to deteriorate, letting water, insects, and small animals into the engine bay. I took some time to design a replacement. It is best to print this with a resin 3D printer. All you need to properly install this is silicone sealant (I used RTV silicone). This is designed to go through the plastic part at the bottom of the windshield and inside the rubber tube that leads to the drain.
I printed mine in Elegoo ABS-Like Mint Green resin with my Elegoo Mars 3 Pro.
