nut and bolt quick release

grabcad

this nut and bolt that can be 3D printed, injection moulded... built with 2 different compounds, the nut and bolt platic (the bold beeing a bit more flexible than the nut.) and the quick release thin metal. The idea is that hammering in the bolt with its quick release in the nut makes a strong fix. To release the system simply extract the quick release system (with a thin flat screw driver) which will cut the dents of the bolt and so the system is free. You can only use this system once, a bit like a tie wrap, this could be very usefull in the automotive industry and for general purpose of quick fittings.
