I'll be happy to do so, I want to properly test it and refine the design somewhat, turns out my bearing is slightly narrower as well so I need to move the wider section of the bearing peg up a bit, it's not much so even if the bearing slips all the way down on my original version it's still in the filament path but eh took seconds to correct in the model once I noticed, need to come up with a similar solution for the top, perhaps a printed washer kind of affair?if I make the peg shorter you an even shorter m5 screw. give me a day or two, I need to design and print a way to mount it to my i3 before I can test it properly. There doesn't seem to be any i3 mounts for this design, a bit weird.
