It's a pen holder! It holds pens! Or anything else that fits in a hexagon that's .625" flat-to-flat. Yes, we're pushing the frontiers of 3d printing! Anyhow, all told it's ~4.438" tall with the base and 3.5" flat-to-flat across the widest hex dimension. Holds 19 items. The base is completely optional but it will spin on the base. You'll need three .25" balls to make it spin. I used stainless, but maybe printing them will work?
