Anchor - nautical key float / buoy

thingiverse

What about crafting something airy and buoyant that doubles as a nautical emblem of something dense and decidedly not meant for floating? I envisioned an anchor designed specifically to serve as a float/buoy for your boat keys. When embarking on a sunny day, taking the boat out for a spin, you don't want your fun to be ruined when you inadvertently drop your keys into the water. The design is fully hollow and all the walls are 2.25 mm thick, making it watertight.
