High-Detail Artistic STL Modeling

I’m looking to transform a set of reference sketches into a high-detail, print-ready STL that will be used as the final artistic piece—no further post-processing or casting, straight from an FDM printer to display.

What I need from you
• A watertight, manifold STL with clean topology and no intersecting shells.
• Wall thickness, overhangs, and tolerances planned for standard FDM settings (0.2 mm layer height, 0.4 mm nozzle).
• Parts split logically if the design exceeds a 220 × 220 × 250 mm build volume, complete with keyed joints for easy assembly.
• One initial concept pass followed by two rounds of revisions to dial in fine surface detail and fit.

Acceptance criteria
– Passes Mesh-mixer/Netfabb repair checks with zero errors.
– Slices in Cura or PrusaSlicer without generating unexpected gaps or islands.
– Prints successfully on an Ender-3-class machine using PLA at 0.2 mm layers.

I’m comfortable if you work in Blender, ZBrush, Fusion 360, or similar—just make sure the final export is a single, ready-to-print STL. Share a couple of examples of previous high-detail prints you’ve produced so I can be confident the model will translate beautifully from screen to filament.
