Dovetail Burr is a variation to the classic mechanical 6-piece burr puzzle. Its six pieces are held together by dovetail connections. The puzzle is easy to solve. The pieces slide in place one by one.
The set of six pieces took about 8 hours to 3D print on a Dutchy 3D printer. 90 gram (30 meter) of 1.75-mm filament was used. The puzzle itself weights 80 gram, as 10 gram of material was used to support the overhanging dovetails. The filament is based on transparent PLA plastic that is infiltrated with 20% wood fibres, giving it a wooden look-and-feel (and smell!). The three types of wood used are birch, mahogany and black wood.
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.
