I personally didn't buy it. My school bought it this year. The machine cost $25,000 and my CAD teacher gave me a copy of Inventer Pro. But for a new box of the plastic wire (printing material) is like $250.00. I also found out how I can hook the wheels up to my FF. All I need is some 14mm hex nuts. If you know anyone who would like to give away or sell four of them please tell me about it. Thanks
