In this build i am using a WTF2040-2 Ball Bearing Nut with associated linear screws and FF15, FK15. I got them cheap on ebay, that's the only reason i'm using them here. Its probably a good idea to modify the design for acme screws, that way you can replace the 80 tooth pulley with something smaller. I needed a 4:1 ratio to slow things down, the screws are just too fast. You wont have this problem with acme screws.
For the rest of the build, its gonna require drilling about 4 holes on the openrail gantry plates. i still have to figure out how to attach the timing belt to the print head and i'm probably going to have to modify the jhead mount.
The rest of the mount can be found here: http://www.thingiverse.com/thing:108273
