Anyone use a direct drive extruder?

Anyone use a direct drive extruder?

I have ordered a couple of these

I am looking for the rest of the parts required.

I really like @Whosa_whatsis design for the filament guide and bearing idler. http://www.thingiverse.com/thing:15718

Is there a design for mounting the motor to the X carriage?

Check out http://qu-bd.com. I like their hot ends, though I don’t recommend their drive gears or idler mechanisms.
