Printable Moderate-Detail Car Model

I’m looking for a clean, printable 3D model of a RC car based on the sketches and other models, I’ll share once we begin. The final piece will be used for 3D printing, so every surface must be watertight and free of non-manifold edges or inverted normals. I only need essential parts—accurate body panels, wheels, window recesses, and the main interior shapes—without the ultra-fine engine or dashboard details you’d add for cinematic renders.

Preferred workflow is Onshape, Blender, Fusion 360, SolidWorks, or another mainstream CAD package that exports reliably to STL or OBJ. Feel free to sculpt first, then retopologise, as long as the mesh stays under control for slicing in Cura/PrusaSlicer.

Deliverables
• One ready-to-print STL (and, if possible, the source file)
• Overall length set to 200 mm; other dimensions proportional—let me know if you’d like a different scale before starting
• Single, watertight shell or clearly separated shells for body and wheels
• File passes basic Meshmixer or Netfabb repair checks without fixes

Send a quick note on how you’d approach wall thickness, panel gaps, and wheel separation, and we can get rolling right away.
