Idea for intrinsically fastening one 3d printed part to another. Could be a parametric or procdeurally generated feature
In the world of 3D printing,... complexity has no cost, so why not incorporate the fastening details into your part rather than use flanges, nuts, bolts, washers, etc. The two parts have a double row of T shaped male and female features to provide secure, strong fastening with a quick twist like the bayonet mount on a camera lens.
