### 🚀 NASA Open-Source Mars Rover Redesign (100% 3D Printable)
This project is a complete functional redesign and upgrade of the open-source Mars Rover (based on Jakob Krantz’s build), fully re-engineered in Onshape for desktop FDM 3D printing and clean electromechanical assembly.

### 🛠 Key Engineering Features
* 100% 3D Printable Architecture: Every single bracket, chassis plate, and suspension link is optimized for desktop FDM printing with built-in tolerances, requiring no specialized metal machining.
* Internal Wire Routing Conduits: Structural suspension arms and pivot joints feature integrated hollow channels. Motor power, steering signals, and encoder cables route completely inside the suspension, preventing wire snags and protecting electronics from debris.
* Rocker-Bogie Passive Suspension: A true 6-wheel kinematic linkage that maintains equal ground pressure and continuous tire contact across uneven terrain.
* Independent 6WD & 4-Corner Steering: Front and rear steering uprights enable zero-turn radius maneuvers, crab walking, and high agility.
* Rear-Mounted Solar Deck: Angled rear solar panel array provides power while keeping the main upper payload deck completely open for cameras, sensors, and robotic arms.

### 🖨 Recommended Print Settings
* Material: PETG or PLA+ / Tough PLA (PETG recommended for mechanical durability and outdoor UV resistance)
* Layer Height: 0.2 mm (0.16 mm for articulated pivot joints)
* Infill: 25%–40% (Gyroid or Grid) for structural suspension components; 15%–20% for body panels
* Perimeters/Walls: 4–5 walls for high strength on load-bearing arms and motor mounts
* Supports: Minimal / standard supports where overhangs exceed 55°
