I have four separate TIFF illustrations—earth, water, air, and fire—that I want turned into four individual STL files ready for 3-D printing of molds with highest precision. Three finished molds( pictures- Earth, Fire, Air-Water with triangles) - 31 mm × 11 mm × 5 mm cubic envelope One finished mold ( picture-Anima with circle) - 31 mm × 13 mm × 5 mm . Walls of the lines are 1.5mm tall, thickness of the walls 0.5-0.7mm Please keep every fine contour crisp; the look needs to stand up to close inspection once cast in resin. The STL model should match 2D drawings- 100%. Key deliverables • Four watertight, error-free STL files (earth, water, air, fire) • High-resolution surface detail that supports 25–50 µm layer heights • Distinct elemental symbol on each model—no additional lettering I will provide the TIFFs immediately; let me know if you need vector traces or reference glyphs for the symbols. Please confirm the workflow you prefer (e.g., Blender, ZBrush, Fusion 360) and your typical turnaround time for the first preview render. Desired turnaround 2-3 days.
