I need a straightforward 3D model of a small plastic part that will go straight to my FDM printer. The piece is quite simple—mainly basic geometries and clear overall dimensions—so no filigree features or complex assemblies are involved. My hand-drawn sketch with key measurements is ready; once the model is built I’ll confirm final sizes and any minor tweaks before we export for slicing. Preferred workflow is parametric CAD (Fusion 360, SolidWorks, FreeCAD, or similar) so I can adjust dimensions later if a tight tolerance needs a slight shift. A clean, manifold STL is essential, but please also include the editable source file. Deliverables • Native CAD file (e.g., .f3d, .sldprt, or .step) • Print-ready STL, watertight and oriented for printing • One quick revision after initial review to fix any small dimensional issues Keep the modelling neat, with chamfers and fillets only where specified, and stay true to the basic shapes and dimensions in the sketch.
