CAD Optimization for Injection Molding (shell & rib modification) Fusion360/STEP

I already have a Fusion 360 .f3d model that has had multiple runs on a FDM printer, but now I need it re-engineered for higher volume injection molding. The overall look, footprint, and fit must remain identical to the current print; only the internal geometry should change where necessary to meet proper draft, wall-thickness, and flow requirements.

Material target
I plan to shoot this in a strong, rigid everyday plastic such as ABS or PC-ABS. If minor tweaks are needed to suit those resins—radii, ribs, bosses, or gate landings—work them in while preserving the exterior aesthetics.

Part configuration
The product comprises two separate pieces that mate together after molding.

What I need:
• Updated, mold-ready Fusion 360 file (.f3d)
• A STEP file for the molder
• Callouts or screenshots highlighting draft angles, gates, ejector pins, and suggested tolerances
• Brief notes on estimated shrink, recommended material grade, and any risk areas

I’ll provide the current 3D-print-optimized file and photos of each part as soon as we start. If you’ve taken printed parts to production tooling before—especially in ABS—your experience will count.

Required Tasks:
Open the .f3d files in Autodesk Fusion to preserve design history
Use the Shell Tool to hollow out the .5inch solid thickness.
Add internal structural cross ribs to cored out sections to retain rigidity.
Ensure appropriate draft angles are applied for clean ejection
Deliver update f3d files and production ready step files

Note: I will not consider automated responses or those from AI agents. I need to see evidence of consideration of the project from a real person as there will likely be a need for discussion of a number of variables concerning injection molding.
