technical assembly 3d model

A simple technical assembly diagram for a concave faceting attachment, drawn in clean hand-sketch style with labels. Show a flat rectangular base plate. On the left side, mount a small DC motor labeled "CAM MOTOR (60-100 RPM)". Its shaft connects to a circular CAM WHEEL with a visible offset pin at 0.5 inch from center. A thin connecting rod links this pin to a SLIDE BLOCK that moves on a LINEAR RAIL (1 inch stroke). On top of the slide block, mount a larger DC motor labeled "SPINDLE MOTOR (5000+ RPM)". This motor's shaft points forward and ends in an ER11 COLLET holding a 10mm DIAMOND ROD. A separate stone holder (IMAHASHI MAST) is shown in front of the diamond rod, holding a gemstone. Use arrows to show: rotation of cam motor, rotation of spindle motor, back-and-forth movement of the slide block (label "1 inch stroke"), and the stone pressing toward the rod. White background, black lines, clear English labels, no shading, like an engineering sketch.
