Hello! I'm hoping to print a MarkIV headset, and am confused about the electrode holders for the MarkIV. Can anyone tell me if the MarkIII bolts are compatible with the MarkIV frame? Thanks!

    No, the Mark IV uses smaller holders that are injection molded. They are too small to print.

    If you already have Mark III bolts, there IS another option, to purchase on Shapeways:

    Thanks for the information! Do you know if the M3 Ultra design is available for home printing? Or is this one only available via Shapeways?

    The 1st Shapeways link I gave earlier, does NOT print in PLA, but instead in SLS nylon (laser sintering). Thus it has the threads built into frame and needs no inserts. It is also much stronger and lighter than PLA. It takes a moderate amount of work to build all the support struts for a PLA build, I doubt that has been done for this frame. In addition it would need modification for thread inserts. So in short, the Shapeways design is not PLA printable.
