The file 'X-Idler For I3 For Use With Leadscrew And 624 Bearing 3D Printer Model' is (stl) file type, size is 871.9KB.
This is a part I've been using for 6 months solid. I tweaked the screw hole to accommodate for a 4mm screw so I could use a 624 bearing. This makes the belt perfectly parallel the entire length!
This model also uses the leadscrew nut with 4 screw holes (I got mine from Folger Tech)
This was a hackjob, just fyi. I hope it works for someone.
