chrome skeleton phone case 3d model

The main design of this custom phone case centers on a biomorphic liquid metal aesthetic, featuring a high-gloss chrome, fluid skeleton structure that mimics molten drip metal while maintaining structural integrity for 3D printing. Engineered specifically for rigid filaments like PLA or PETG, the case replaces traditional solid flexible walls with an open, sculpted skeletal frame. It incorporates reinforced, impact-absorbing corner bumpers integrated with subtle relief notches that enable a tight snap-fit installation on the device without scratching the chassis or risking material shear. The rear features a precise raised lip around the camera cutout to safeguard the lenses from flat surface impact, while wide open cutouts maintain full accessibility to the USB-C port, speaker grilles, and side physical buttons. Smoothly filleted organic contours eliminate sharp geometric edges, minimizing steep overhang angles to guarantee clean FDM layer deposition with minimal support structures.
