RC sailboat cap (bayonet)

thingiverse

Here's a cap I built for the electronics hole in my RC sailboat's hull. It's engineered to keep water out and provides a secure fit with its bayonet coupling, locking it on tight. The concept behind this design was to give my boat a look that's reminiscent of a real racing vessel. To ensure no water enters the boat, I applied silicone to the top of the cap.
