Wow Eddie, do really think this is more aesthetically pleasing? In any case I applaud his efforts but the semi-enclosed environment of U2 does server a purpose. I am also curious if he kept the same bowden extruder design, which I find to be the biggest weakness of the U2. If I still had mine, I would replace it with the BondTech extruder. https://youtu.be/JuenK5ohlDE
