Screw Burr is related to the classic six-piece burr. However, screws are used instead of square rods. Because of this, pieces are not slid, but screwed in. A wonderfully colourful 3D-printed variation that has been made by Oskar van Deventer. The set of six pieces took 6 hours to 3D print on a Dutchy 3D printer. 88 meter of 1.75-mm colourful PLA filament was used to print it. The puzzle weights 42 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.
