3D Model & CNC Prep

I need a precise 3D model of a small mechanical part that will serve as a direct replacement for a worn-out component. I no longer have the original piece, but I can supply clear sketches and rough dimensional drawings. From those sketches you’ll create a production-ready CAD model, make it watertight for 3D printing, and generate tool-paths so I can cut the same geometry on my CNC mill.

Here’s what I’m expecting:

• A fully parametric CAD file (STEP or SolidWorks) reflecting the dimensions in my sketches.
• An error-free STL optimised for FDM printing, with tolerances dialled in for a nice slip-fit once printed in PETG.
• CAM output (Fusion 360 preferred, but Mastercam or similar is fine) with tool selection, feeds, speeds and roughing/finishing strategies ready to load on a standard GRBL-based CNC.
• A simple PDF drawing that calls out the critical dimensions so I can sanity-check if I need to tweak anything later.

I’ll provide the sketches, material notes, and the mounting points that must align with existing hardware as soon as we start. If you spot ambiguity in my drawings, flag it early so we can fix it before you run simulations. The part is straightforward—no exotic surfaces—but accuracy matters because it mates with steel shafts and bearings.

Deliver the files, I’ll test-print, dry-fit on the machine, and then run your G-code on a piece of aluminium. When everything bolts up without play, the job is complete.
