Hi, I'm building a kayak and would like to put a compass on the deck.

The kayak is designed by Björn Thomasson and he has also made this design.

But as you can see from my attempt I could use some design input.
The idea is to 3d-print the parts and laminate them with glassfiber and epoxy.
Since the deck is rounded I'm letting the two parts overlap so I have enough material to cut away when putting it on the kayak.

I do want it low profile and a bit subtle, but I think it looks rather boring the way I have done it.

All ideas are appreciated.
