I need this plastic piece with the spring underneath it. Notice this one has fractured. It's working for now, but I'm backlogged with prints and the last thing I need is for it to fail and not have a replacement. I doubt this is a universal part that is available online, but I figured I should check with you guys to see. I called Robo, but of course "nobody is available to take your call, please call back". I left a message but no idea when I'll get a reply.
