rubik's cube 3d model

Create a 3D printable model of an electronic Rubik’s Cube. The cube must have the external appearance of a standard 3×3 Rubik’s Cube, with separated pieces (centers, edges, corners) but simplified geometry for printing. Inside the cube, generate a hollow spherical or cubic core with enough space to contain a microcontroller (ESP32 or Arduino Nano), a small LiPo battery, and wiring. Each of the six center pieces must include a cylindrical cavity to host a Hall sensor or small magnet. The core must include six radial mounting points aligned with the cube faces, each with a flat surface to place sensors. The pieces must interlock using simple sliding or snap-fit joints suitable for FDM 3D printing. The external pieces should have a 1 mm recessed area to apply stickers or colored tiles. The model must be dimensionally consistent: total cube size 60 mm. Avoid overly complex mechanical mechanisms; prioritize printability and internal space. Output a clean, solid, watertight 3D model suitable
