    I don't think there is an STL or 3D model of this available.

    Personlly, I am very surprised this isn't a bigger issue, the spring used is overly strong requiring a lot of pressure to open that idler arm. You are going to have to call Robo and get a part sent to you.

    For the R2?
    No. AFAIK, nobody has reverse engineered the Robo CAD files yet and Robo has not released them for any recent printer versions (nothing since the R1)

    My R2 isn't running today or tomorrow (maintenance ) so I'll model it up for you if you need.

    wow. I wonder if the screw that holds it in, backed off a bit, and when you applied pressure, it somehow torqued it?
    Mine got very loose and was causing under extrusion, until I discovered that behind that flat cover, was another allen wrench screw that was really loose. Tightened it up, and my extrusion probs went away.

    Once you get a model someone can print it for you. I think we can find someone around here who can do that ... maybe :)

    give this one a shot. I have it installed and running on my R2. I omitted the back pin and made solid so its easier to 3D print. Seems to work fine. Can add the pin later if an issue shows up, let me know.
