Low-Detail 3D CAD Prototype

I have a set of hand sketches, a short design brief and a 3-D scan of the product I want to prototype. The scan is already close to the right proportions—overall length 8 cm—and I have listed each segment’s circumference so you can confirm dimensions as you tidy the mesh.

What I need from you is a clean, printable CAD file that captures the overall form without unnecessary fine features. This will be a low-detail 3D model intended purely for a first-run prototype, so please keep wall thicknesses and tolerances suitable for common FDM or SLA printers.

Key points
• Work from my scan, sketches and notes to rebuild the geometry
• Respect the given segment lengths and circumferences
• Deliver a watertight model ready for slicing (STL) plus the editable source file (e.g., STEP, SolidWorks, Fusion 360—use whichever package you prefer)

Once I receive the files, I’ll run a quick dry-fit check in my slicer; if everything aligns with the 8 cm overall length and the segment proportions, the job is done.
