Original version is the exact same thing that you can download from IGUS website. I just enlarged the center hole for PLA printing. It should fit perfectly on a 8mm rod, at least for my MK2.
V2 is the modify version from the original, I read somewhere on the internet that said this pattern works better than the original. I cannot really confirm that or back this up. But if you are interested in trying it or test it, you can download this version.
I do not actually design this bushing, all credit goes to IGUS or whoever design it. Again, Happy Printing.
Upload the 10mm version since someone ask for it.
Design to print in PLA because it seems to work the best compare to other filaments. Print best with 3 perimeters and at least 10% infill. Layer height does not matter.
