I've noticed you printed this in 2 sizes (one is scaled smaller than the other). the original size is designed so that the groove for the nail that secures the wheel is the same length as the block of wood that would come in a kit. the fenders will cover the majority of the wheels, but not all of it, to maintain the width total width of any derby. I guess what I'm trying to say is, if you print less than 100% scale there will be a larger gap between the wheels and the rails and the derby will snake its way down the track.

I didn’t print at 2 sizes. The photo is 2 photos spliced together of the same print flipped over. If you print less than 100% the wheels won’t fit under the fenders and you wouldn’t be able to add enough weight inside to meet the weight requirement.
