Create 3D model of the grey plastic case similar to those used in classic instruments. The attached file gives numerous examples. Only model the basic case, not the instrument display or the black buttons on the bottom. Leave off identifying manufacturer name or marks.
Deliver the mesh model in a format compatible with Photoshop CS6. You may use any 3D modeling tool you wish. Render the result in Photoshop and deliver web ready images (PNG) format in 100x100, 150x150, 250x250, and 1000x1000 pixels. Provide the original mesh format, Photoshop files, and png output.
