Doomforge’s Wheels/Drive

So when I ordered these omni-wheels, I thought they had a shaft diameter of 4mm, but they actually had a 5.5mm diameter and a 4mm length. 

The wheels came with 2 different hubs, the 5.5mm D-Shaft and a Lego hub. So I drilled the Lego hub out to 4mm and now it fits nice and snug on the motor shafts (but I may glue them in place later just to be sure).

You can also the motor brackets that attach to the front of each motor.
