mechanical hinge 3d model

A precise 3D mechanical joint template and functional CAD utility tool called a 'Flexi Cutter' for print-in-place articulated models. The model consists of a perfectly flat, thin rectangular dividing plate in the center. Intersecting directly through this dividing plate is an interlocking hinge mechanism: on the left side of the plate is a solid, clean cylinder, and looping cleanly around it from the right side is a thick, solid torus ring. The entire mesh must have smooth, perfectly manifold engineering geometry, flat flush surfaces, sharp mechanical edges, and zero organic or soft textures. It is an abstract, mathematical CAD block designed strictly for boolean subtraction modeling.
