I printed this in the hopes of getting an E3D head and experimenting with it. I think my Rostock Max prints great but always open to ideas. I printed two at once. This print took my RM 2 1/2 hour. Will update this post once I get a head.
I was planning on trying this. Did you have any success with it.
I never got the head at the time I downloaded and printed the part. they were sort of hard to acquire then too and my stock head prints great. But the parts do align with stock parts and would probably work with any j head.
