Otto HP wrist band track chassis

Do you feel your Otto deserves more freedom of movement? Upgrade it into an "all-terrain" vehicle with this custom undercarriage! Using common silicone wristbands as tracks, your Otto can now conquer obstacles and navigate rough surfaces like carpets or bedding. You can even use the rear attachment point to pull a cart!

• No Modifications Required: The original chassis remains untouched. Everything attaches to the body using existing holes and standard screws.

• Accessible Materials: This mod uses ubiquitous 210mm silicone fitness wristbands as caterpillar tracks. When placed on the custom barrel-shaped wheels, they stay indexed "almost magically."

• Hardware Needed: Beyond the printed parts, you only need M3 screws.

• Compatibility: Originally designed for the Otto DIY, I have now adapted this version specifically for the Otto HP. Both STL files are included in the download.
