Official vessel number plaque for vessels registered with USCG.
Features built-in fillet to make it appear seamless with the surface it's glue to.
Can be painted over, then sanded down to reveal the number again.
Free and open-source, designed in ShapeScript.
Best if printed out of something light and strong. Can be made using two different materials (one for the body, the other for the text).
The author marked this model as their own original creation.
