Any tips for connecting 3mm D shape shaft to 80mm or 64mm Mecanum Wheel Sets

I plan to purchase either the 80mm or 64mm Mecanum Wheel Set but my shaft diameter is 3mm any tips on how to achieve this?

Thanks

Adding a little more detail.

Are these the correct hubs:

To connect to these wheels when the motor axle is 3mm diameter?

Hi @paulcart and welcome to our forum.

Using a hub is the best way for sure.

The one that you chose could work.

Your shaft is 3mm and the hub is for 4 mm. You would have to add some material on the shaft to make it fit tightly.

Also, if the four threaded holes are not matching with the holes om the wheel you choose, you just have to drill new holes according to the pattern.
