The "Impossible bolt and nut" is an amusing 3D-printable two-part assembly with a working thread, where a nut is trapped on a bolt.

The single STL file contains ... [READ MORE] the nut placed at a slight distance from the bolt's head. The gap between both is sized to create a "skipped" layer thus making a fracture plane so that the nut can be removed from bolt's head.

We have supplied several STL files scaled to commonly available 3D-print heights. Please choose the one that closest fits your desired print height. It is possible to scale the STL up or down with successful results.

Please see instructions for more information on how to 3D-print this bolt and nut. Also note that some slicing software and settings could interpret the air gap as an STL defect and remove the gap during print. You will have to disable the STL heal function.

Download the STL files and 3D-print your own! :)
