OK only down side is I don’t see how he kept the costs under $50 with the threaded rod he used and some other parts. But most likely had stuff “around” already. Oh and the couplers for the steppers…I could totally see this more around $100. But its a nice build overall. I like the CD drive for the Z. Only down side there is the torque it can do is pretty limited.
