Mine cart for Minecraft toy figures

This mine cart is scaled to fit the toy Minecraft toys being sold in stores. I will be adding tracks and wheel soon. I have two sets of wheels. One with no axle and the other with. This saves time if you have a rod or something to use as an axle. I wonder if I could make this use the wheels from a HO scale train car. If I can find some wheels to try I will make one that uses those wheel and then the cart could use HO scale train track. Plus the wheels would roll very well. Let me know what you want made next!
