Design a 4WD robot body 3D model with the following details:
- Rectangular chassis (150mm x 120mm x 4mm), top plate (same size, 3mm thick), bottom plate (same size, 3mm thick)
- Add M3 bolt/nut through-holes (3.3mm) at each corner, and standoffs (6mm diameter, 10mm height, 3.3mm center hole) for plate connections
- Include four TT motor mounts (22x27mm) on the sides
- Add mounts for Raspberry Pi (85x56mm, 4 holes 58x49mm apart), Arduino UNO (69x53mm, 3 holes 54x34mm triangle), 18650 dual battery holder (76x40mm)

A 4WD robot chassis for 3D printing, designed with robust frames, mounts, and cases for hardware installation. Exclude wheel and motor shapes; instead, add precise housings, brackets, and mounting points for TT DC motors (body 70x23x18mm, shaft hole 6mm, M3 holes 10mm apart, with 0.5mm clearance) and 60mm wheels, allowing easy attachment. Also, include a secure battery house for 2x18650 cells (holder 78x42x22mm), with retention clips and access for wiring. Add all necessary bolt and nut holes (M2, M2.5, M3), cable routing channels, strong support beams, and clear, practical sockets for real hardware installation. Use distinct colors for each mount, and ensure all sizes match these specifications for easy assembly with real parts.

Design a 4-wheel robot chassis, 350 mm wide and 400 mm long, for outdoor use.
Use 4 DS3230MG servo motors (6 mm shaft), 2 on each side.
Mount 125×58 mm terrain wheels so they are outside or flush with chassis width.
Include correct servo mounting holes (per DS3230MG datasheet).
Center area (200×300 mm) must hold battery and electronics.
Add cross supports to reduce flex on rough terrain.
Material: 3 mm aluminum or 3D printable PETG/ABS with support ribs.
