Works as advertised. To have any real traction you'll have to do something to the wheels. I used small rubber bands stretched around the rear wheels for traction.
Maybe it's because I'm using Cura, but the wheel file has the wheels standing up on end. I tried printing them once that way (Monoprice Mini Delta) and failed miserably. Laid them down flat in Cura and then printed with no issue.
Fun project! I created an account just to give you props. :)

How do you ensure the wheels and firmly joined to the axle? I intend to use PLA for printing.

I used PLA as well. My axel had a small "tab" at the point where is was attached to the brim. I used pliers to smash the tab down a little bit. I ended up with a solid fit.
