The prompt
Design a premium, rugged, 3D-printable handheld case called REDNINE for a Raspberry Pi 4 with a 3.5-inch GPIO touchscreen. Style: stealth military cyberpunk, matte black with white accents. Sculpted angular panels, ergonomic grips, bevelled corners and a flush screen bezel. Integrate subtle hidden Masonic geometry: square-and-compass shapes disguised as panel grooves, sacred geometric patterns and a small all-seeing eye concealed in the rear ventilation. No obvious Masonic logos. Use black PLA for the main shell and separately printable white PLA inserts for fine trim and REDNINE branding. Keep all Raspberry Pi ports accessible. Provide top USB access and a support cradle for an external ALFA dual-antenna Wi-Fi adapter. No keyboard or mouse. Create separate printable front and rear shells, removable screen bezel, screw mounts, ventilation and realistic internal clearances. Use 3 mm walls. Make the design mechanically practical, not just decorative.
