nail sorting machine 3d model

A 3D model of a mechanical, gravity-fed nail sorting machine designed for 3D printing. It features a high, angled starting funnel at the top. The funnel leads into an inclined sliding ramp. The floor of the ramp has a series of sequential rectangular gaps that get progressively longer from top to bottom. Directly beneath each gap is a square collection box to catch the falling nails. Clean geometric shapes, smooth plastic texture, functional mechanical design, isolated on a solid background.
