retro computer 3d model

A retro Macintosh-inspired desktop mini computer shell designed for a Raspberry Pi 4 and a 7-inch HDMI touchscreen. The object should look like a small vintage computer with soft rounded corners, a slightly chunky body, a clean front face, and a rectangular screen opening centered on the upper front. Below the screen, include a subtle lower front panel like a classic Macintosh. The back should be thicker to contain internal electronics. Add simple side ventilation slots and a removable back cover. The design should feel minimal, cute, functional, and slightly futuristic, with smooth plastic surfaces and an off-white industrial design aesthetic. Stable base, balanced proportions, suitable for 3D printing, no keyboard, no mouse, no extra accessories, single-piece main body with detachable back panel.
