I have a concept line of minimalist lampshades that will be manufactured on a desktop 3D printer, primarily in pla. I need the complete digital design work—from clean, elegant geometry through to watertight, print-ready files—so I can move straight to prototyping. The overall aesthetic is pared-back: simple silhouettes, no ornament, and surfaces that diffuse light evenly. Final models should be optimized for PLA (or comparable plastics), with wall thickness, ventilation and support considerations already built in. Although the first run is plastic,; in that case I prefer a matte finish, so please keep that surface treatment in mind when choosing textures or suggested post-processing. Key deliverables • 3–5 unique minimalist shade designs • STL (and optional OBJ) files ready for both FDM and SLA printing • High-quality renders for each design to preview light diffusion and scale • A simple assembly diagram showing how each shade interfaces with a standard E26/E27 socket • One revision round after initial review Acceptance criteria • All files pass common slicer checks without repair • Wall thickness no less than 2 mm unless structurally justified • Maximum build-plate footprint 200 mm × 200 mm × 200 mm • Even, glare-free light spread demonstrated in render or quick physical prototype Please base your work on reliable CAD tools such as Fusion 360, SolidWorks or Rhino, and supply editable source files alongside the final exports. Once the above points are met, we’ll green-light printing and move on to colour and finishing options.
