I thought about getting my dad a scale model of his boat for his b-day, but he's selling it now so maybe ill do it for the next one. Or get scale models of his first couple boats as a memento.
the sculpting machines that you're reffering to, are they the onle that 3D print with a type of plastic, or cut away from a piece of metal? Both are pretty cool.
