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.
