I already have the model in a s STEP file, but it still needs the last mile of clean-up so it will print perfectly on my SLA machine. Because this is a decorative item, the surfaces must be flawless, the walls consistent, and the whole body completely watertight with no hidden non-manifold edges. What I need from you: • Inspect the geometry, fix any errors, repair thin walls, and hollow where sensible to reduce resin use without sacrificing strength or fine detail. some fetures on the enclosure which are very thin can be removed and replaced with a drawing. via stickers/sketch pen drawings. those must be drawn in dxf/svg inside editing software or in adobe illustrator. • Add or suggest drain/vent holes appropriate for SLA. • Return a production-ready updated STEP so I can keep an editable version for future tweaks.
