The airtripper is indeed a good extruder. I love it with the MK8 gear to drive the filament.by dkulinski - Smart_Rap
The press fit are for the bowden tube. My e3d-lite6 doesn't need a pressfit connector, so I only needed the one. You are looking for something like the following:by dkulinski - Smart_Rap
Are you sure your stepper motors are 400 steps per revolution? The ones I use are and I set the steppers to 1/8 microsteppping for more torque.by dkulinski - Smart_Rap

Sorry I am a bit late on this, here is the link to my Youmagine page on the design and the modified JSCAD file: mandrav, it looks like we made the same changes! sethmo, I suspect that the reason on side fits tightly is due to the fact that the "washer" size is a fraction. I want to rework the head to make this a whole number regardless of the bearing size.by dkulinski - Smart_Rap
I also printed out the v1.2 head and the troughs are not big enough for LM8UUs on the top. The length is hardcoded to 19mm which is the length of a lm6uu bearing. On top of that, my printer had a partial jam and one of the sides in the bottom bearing holder missed part of layer and was very weak and ended up breaking. I tried to modify the JSCAD file, but there are still lots of tweaks needeby dkulinski - Smart_Rap
