I need two circular speaker grills modeled for resin printing: • Grill A: 430 mm diameter • Grill B: 330 mm diameter • Shared spec: overall thickness no more than 15 mm The look I’m after is a detailed geometric pattern—plenty of open air, minimal material, and small, evenly distributed holes for sound transparency. Please keep the structure thin yet sturdy enough for a typical SLA/MSLA resin print. Deliverables 1. Separate, print-ready STL files for each grill 2. Design sized exactly to the dimensions above, centered at origin 3. Surfaces manifold, with wall thicknesses appropriate for resin (no paper-thin artifacts) A simple screenshot or quick render showing the pattern on each grill will help me confirm the aesthetic before final export. I’m aiming for a straightforward, print-ready model rather than an elaborate production kit, so efficiency and clean geometry are key. If you’ve designed lightweight speaker or ventilation covers before—especially with geometric motifs—let me know; that experience will be a plus.
