Review on 🔧 UGEARS Combining Mechanical Construction Kit by Ken Wilson

The gear train is set in after the shell has been crushed, resulting in an absurd amount of effort required to keep all seven axles from slipping out of their respective holes or worse nor break tip of a toothpick. Very little guidance is given on how to properly align the gears and no information at all is given on how to add a rubber band reverse drive. Stronger toothpicks would be nice, but a design that doesn't require trying to pinch them. in general it would be better. At least when stationary, this is a good combine harvester model.
