On older Ducati models like 750SS Nuda/900SS Nuda there are small angled rubber plugs to keep moisture out of the headlights an grant a small airflow.

These parts are very rare to find (in my case impossible to order), so i created them by my own with some fixes to be able to print in a proper way. I used Filaflex 82A. Its printed with support.
