I have four drawings—supplied as JPG / PNG—that I need turned into clean, watertight STL files for 3D printing. The end use is physical prints, so the geometry must be high-precision: crisp edges, smooth curves, and no mesh defects that could trip up a slicer. A few dimensions will have to change from what you see on screen. Once you’ve done an initial pass, I’ll give you the key measurements to dial in; everything else can stay in original proportion. Deliverables • Four individual STL files, each verified as manifold and ready for print • Adjusted dimensions reflected exactly as provided in the follow-up spec • Screenshot or viewer capture of each model showing overall scale and critical measurements for quick reference I’m comfortable if you work in Blender, SolidWorks, Fusion 360, or any other professional tool—as long as the final export is solid and printer-ready. If this sounds straightforward for you, let me know your typical turnaround and any clarifying questions.
