I would have to take a look. You would also have to use makerbot gear drive to make it fit right.

Yes it would... this style of Hobbed Gear Wheel is very typical in this type of extruder. I've sold quite a few of these and only had 1 return (and that was because the buyer had modified his printer so much that it would no longer fit because of additions he had made). Here are some of the places the kits I've made have been sent.
