Description
PDFThis bolt can be used instead of the 70mm M3 bolt required for the puzzle. The bolt is printed horizontally to make it strong enough to survive being manhandled by frustrated puzzle solvers.
It also has a printable nut that can be screwed on by hand, however it can be very stiff to screw on, especially the first few times.
A spring is still required for the puzzle box to function correctly.
Print with 4 perimeter lines for best results.
