I transitioned my detailed 2D sketch into a solid 3D part by executing a clean extrusion of the main controller faceplate.

I discovered that the Shell tool is a much more efficient way to create uniform walls than trying to offset complex intersecting lines in a sketch.

I successfully used the Shell tool to hollow out the solid 3D block, turning it into a true lightweight controller housing with an empty internal cavity.

I set up my workspace to look directly at the inside ceiling of the empty shell and prepared to sketch the five-millimeter mounting bosses that will hold my joystick modules in place.
