Wheels for Mini Track Loader RC

I haven't tried flexible filament, and my lego tracks are in the mail, so I used the original models to make some wheels. The little nibs are just about as small as they can be, with 0.2mm layer height and a 0.4mm nozzle.

In hindsight, I should have made the OD larger, so it would have similar clearance to the track. Oops. If you feel like editing it, I'll also add the .step file. It will probably be a pain with all those nubs on it... Maybe scale it up, and then shrink the servo and screw parts? If you do, please post it back here so the next guy doesn't have to.

BTW, there are some very fun things to print with this model. I made a game, trying to clear out all the obstacles with this mini loader, and here are the parts that I used (it was for a fall party):
