CAD Design for Resin-printed Jewelry - 22/06/2025 04:45 EDT
Budget: $30 – $250 USD
I need a jewelry CAD design optimized for resin-printed lost-wax casting (bronze/silver), easy to pour in one go, for a minimalistic, unisex charm bracelet. Specs:
Snake Chain & Clasp: Design a 20.8cm snake chain (4mm thick, 5mm segment length, 8mm spacing) and lobster claw clasp (8mm x 2.7–3mm x 1.5mm) as a single 3D model. Include a 2mm loop, 0.8mm pivot, and 4mm x 2mm logo area (0.1mm deep) on the clasp.
Files: Provide STEP files (Rhino/SolidWorks compatible) for UK use, with 0.1mm tolerance for 4mm OD, 1mm thick rings (4.2mm ID).
Optimization: Ensure SLA printing with minimal supports; include space for 5 charms (10mm diameter, 8mm height, 5mm holes) and compatibility with 6.35mm flange, 4.2mm ID grommets.
Grommets: Separately design 7 grommets (6.35mm flange, 4.2mm ID, 0.5mm thick) as a multi-cavity mold model, with “TRNQLTY” engraving (0.1mm depth).
Clasp Assembly: Design a 0.8–1mm hole in the clasp for an M1.6/M2 set screw (2–3mm long) as a pivot/tensioner, enabling easy assembly with a screwdriver (no torch).
Bonus: Include a 4mm OD, 1 mm-thick closing ring.
Finish: Note brushed finish texture (0.05mm scratches) for post-processing.
Optional: Make the chain scalable (e.g., 21.8cm with 29 segments) for multiple lengths.
