A while ago I ordered an E3D Titan extruder based on Toms recent video. I'm, getting ready for its arrival by printing some bits and pieces I think I might need. A 2mm spacer is required between the Nema 17 stepper motor and the extruder so I've print a few things I could used.
Like in Tom video I'm going to try the pancake Nema 17 to drive the extruder. A link is available on Tom site or if you're in Australia you can use http://au.stepperonline.com/stepper-motors-nema-17-stepper-motors-c-1_21.html
