I’m preparing clear, intermediate-level training material that walks through recreating a hydroponic net-cup holder sized for standard 4-inch PVC. I will supply you with the reference STL; your job is to model an identical part in Fusion 360 and capture every step as a screen recording with on-screen annotations (no voice-over needed). The tutorial must focus on the actual modelling workflow—sketching, parametric features, fillets, shelling, and any tricks you use to match the reference geometry—so that I can understand exactly how to build the part from scratch. Deliverables: • Annotated screen-recording video in 1080p (mp4) showing start-to-finish modelling in Fusion 360. • The native .f3d file created during the recording. • A brief text summary noting key parameters used for the PVC fit. Acceptance criteria: the finished Fusion file, when exported as STL, must overlay perfectly with my reference STL and slot cleanly into a 4-inch PVC tube in a quick digital interference check.
