Screwballs Too is a variation on the earlier Screwballs design. This version uses rhombic dodecahedra instead of balls. This makes the puzzle easier to 3D-print or machine. The object is the screw the six identical pins into the four balls, which are all different, and form a tetrahedron.
The set of pieces took 11½ hours to 3D print on a Dutchy 3D printer. 24 meter of 1.75-mm wood-filled PLA filament was used to print it: birch, oak, mahogany, green and black wood. The puzzle weights 105 gram.
Oskar van Deventer has created many different puzzles including his brand of Oskar Puzzles which are mechanical puzzles and objects that can only exist thanks to 3D printing technology. Since 1978, he has been creating hundreds of mechanical puzzles, making him one of the world's most prolific designers. Several of his innovative designs are commercially available.
