I need a complete 3D CAD model for a wall-mounted rack system that will be produced in plastic and live in my 3D-printing workspace. The design must respect plastic-friendly constraints—think sensible wall thicknesses, chamfers for easy print removal, and parts that stay within a typical desktop build volume or split cleanly into interlocking sections I can glue or bolt together later. Snap-fits are welcome if they make installation easier, but standard screw-through flanges that hit wall studs will work just as well. Deliverables • Parametric 3D CAD files (Fusion 360 or compatible STEP) • Print-ready STLs for every module • Exploded drawing or PDF with critical dimensions and assembly notes • Two to three rendered images for quick visual confirmation Please aim to send an initial concept within a week; we’ll iterate once or twice before you hand over finals.
