We built these wheels after we got tired of re-treading our Vexpro wheels.
The idea is that they split in half off the axel, so the axel doesn't need to be pulled out (We use a 2x1 Aluminum extrusion on both sides of the wheel axel) Then we can easily drill out the pop-rivets and replace the tread. As of now, we have had no issues with the tread bubbling at all.
The hex was broached after this picture was taken, we built 4 of them in house (3 Axis CNC), then a sponsor built the other 4 (5 Axis CNC).
And all the Conversational code to build these wheels was hand written, which is pretty cool!
