Modular Lattice Wheel for All-Terrain Mobility-V2

Follow me on MakerWorld for more of my designs, drops, and future releases! : makerworld.com/en/@3DMakerSpace/upload

Originally developed as part of a technical research project for Martian rover mobility, this wheel system addresses the extreme demands of extraterrestrial terrain—loose regolith, thermal cycling, and structural fatigue from impact. This release brings the core design to MakerWorld, scaled and adapted for 3D printing by hobbyists, educators, and robotics enthusiasts. A detailed description of this study has been attached as an assembly guide. Feel free to check it out to know more!

🔧 What’s Included:

• A 50% scaled-down print profile (can be scaled up for larger builds).
• Parametric negative cylinder cutout to accommodate axle rods—adjustable to your rod diameter/depth.
• Modular TPU lugs (V2) with added padding, based on Finite Element Analysis (FEA) for better wear resistance and load handling.
• Optimized for dual-material prints: e.g., PLA/ABS for the frame, TPU for the flexible lugs.

🚀 Why This Is Useful:

• For robotics developers: The modular tread-lug architecture allows easy customization for different terrain types—ideal for DIY rovers or off-road bots.
• For educators and STEM programs: This model demonstrates key engineering concepts—topology optimization, modularity, material properties, and FEA-informed design—in a hands-on way.
• For the MakerWorld community: It's a functional, upgradable platform. You can test different infill patterns, TPU durometers, or scale it up for your own outdoor robot.
• For space design enthusiasts: Inspired by real Martian challenges, this model brings aerospace-grade thinking to your workbench.

The current V2 lugs are the result of FEA studies that showed increased durability and reduced stress concentrations under wheel loads. This makes the V2 design more robust for real-world terrain, even in scaled or Earth-based use.
NOTE: Since being printed in PLA or TPU, remove the support structures carefully.
