Been 3d printing lots of fun dodads. Favorite so far are my cup holder caddies for my smaller boat. I was sorely lacking in convenient places to set things.
Sized it large enough to fit bigger water bottles and coffee mugs as well.

At some point I'll show how I'm actually mounting it. The white brackets at the top are just attached to the carpeted wood pad that's there to be a clamp spot for the rod holder. The clamps hold it up so the weight of the cup holder doesn't drag it down.
The back side of the cup holder caddy has two vertical dovetail slots. They slide onto a heavy duty (printed with carbon fiber filament) base and snap in.
