I printed this and the overall build ideal is good and it does work. Though the only problem I had with it was the little posts that hold the wheels broke. I looked at and though it over and I think a revision of the post would be better. Possibly make them solid with a slight pressure fit to slide into the bearing instead of the 4 small pieces. Also, I think maybe adding a little information and maybe some recommendation of filament or settings to better the overall parts would help too especially for like first-timers.
