woofer speaker 3d model

A simple, clean 3D model of a woofer speaker driver for 3D printing. The design is a solid, monolithic circular chassis with a smooth conical cone in the center and a small hemispherical dust cap. No mesh, no front grill, no wires, and no logos. Completely smooth surfaces. On the top edge of the circular frame, there is a small, thick integrated solid loop for a keychain. Minimalist geometric style, watertight mesh, optimized for STL export and 3D printing. No holes on the outer rim
