I perfected the joystick openings by modifying my 2D sketch to size the two thumbstick holes to exactly 21mm, ensuring my controllers will have a full range of motion without any mechanical binding.

I learned internal component layout strategies by mapping out the step-by-step logic for transforming a flat faceplate into a 3D shell, including using mounting bosses for the joysticks, building an internal cradle for the battery, and cutting precise slots for the power switch and programming ports.

I mastered the Inventor interface by navigating Autodesk Inventors Modify panel to locate the Offset tool right next to the Stretch command.

I prepped the 3D shell geometry by setting up my active workspace to transition my flat sketch into a hollowed-out 3D top housing with a strong, uniform wall thickness.
