Just got these in to go with the new control board. I’m definitely bummed this isnt my printer 
What flavor of printer are you building? Dual Bondtech’s is seriously bada$$ !
CoreXY with a bit of a twist
Are they injection molded now?
Nope. Still 3D printed. Injection molding these would be quite expensive. You can still 3D print these yourself though. The files for the V2 extruder are on the bondtech website. The only difference between the V2 and the QR is the quick release.
