My AeroGlide Staggered Omni Wheel V1 (4WD System)
I engineered this premium, high-tech industrial omni wheel completely from scratch to solve vertical rolling vibrations on robot cars. I am a 12-year-old designer, and I optimized this entire system inside Tinkercad using precise mechanical clearances.
How My Design Works
My 45-Degree Staggered Dual-Tier Geometry: I stacked two 4-spoke asterisk layers and rotated the top deck by exactly 45 degrees. This ensures that a roller is always touching the floor, giving my 4WD car a completely smooth rolling footprint.
My Dual-Material Friction-Free Cartridge: I split the roller into two separate parts to reduce error. I designed a high-precision, ultra-thin 0.3mm rigid PETG inner core sleeve that presses tightly inside my soft, shock-absorbing TPU flexible outer barrel tire.
Zero Bearings Needed: The PETG sleeve rotates directly over my 3.0mm hub axle pins. This creates a low-resistance, smooth plastic-on-plastic interface that prevents my continuous rotation FS90R servos from stalling, eliminating the need for expensive or heavy metal ball bearings!
My Recommended Print Settings
Hub Frame: PLA or PETG (I use Tree/Organic supports for the floating upper deck with a 0.2mm Z-distance so they snap off cleanly).
Inner Sleeve: PETG (Turn on "Detect Thin Walls" and use 1 perimeter wall count for a perfect 0.3mm slice).
Outer Tire: TPU (Print slowly at 20-30 mm/s so the flexible plastic doesn't jam).
