Screw Pack is a colourful packing problem. The object is to fit the seven screws flush into the big nut. The pieces have been designed in a misleading way, such that many packing fit partially, but then the last few screws don't fit. This makes it a confusing puzzle, even when the pieces are easy to distinguish by their color.
This attractive puzzle has been 3D printed by designer Oskar van Deventer. The set of eight pieces took a bit over 8 hours to 3D print on a Dutchy 3D printer. 28 meter of 1.75-mm colourful PLA filament was used to print it. The puzzle weights 82 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.
