MUST BE FITTED WITH 20T TEXT ON TOP AND THE SHAFT IN THE LOWER POSITION WHEN INSERTING INTO X_IDLER
Fits e3d and gates 5mm id/ 20t / 15mm od idler.
Tested on the mk3 passed calibration and all my print test.
Its longr then the original one so you may need to tighten the belt a notch in the extruder if you have the old one installed already.
It will pass calibration even if its out by a mm.
Hope this helps solve the 16t idler issues.
