This twistable 3 inch tall box was turned from walnut and contains a 3D printed 'venus trap door' inside that opens and closes as the body of the wood turning is twisted. The 3D material is wood-based plastic (PLA) fiber that is sandable and can be stained. If you look at the thumbnail, you can see the lid in the closed position and an example of a 3D printed part similar to the interior pieces. The 3D printer cost only ~$200 (Creality Ender 3), not much more that a couple of good turning tools! Here's a link to the 3D printed part site for the interior mechanism:
