This is an example of how you can use AnyShape to make a special bolt or clasp. Perhaps make a clasp that you have lost or one with a more user friendly grip.
It is also possible to cut threads in AnyShape. It is recommended that you use rubbing alcohol or water as a coolant when you cut the thread otherwise the AnyShape may melt due to the frictional heat. It can be useful to give the clasp a little oil, because it may get a little tight.
