Microswiss smooth idler arm

In search for the holy grail of fixes regarding what is mostly known as issue 602 (inconsistent extrusion stuff) I had the idea of trying out a smooth idler on the microswiss DD, it fits a 624zz bearing held in place by M4 bolt.Goes without saying that I didn't solve anything, but if anyone wants to giev it a go here it is.I modeled it with a sacrificial support layer for the hex nut hole, you're supposed to just poke it out.Enjoy!
