E3D (Gates) 20T Idler compatible mount for Y-Axis on Prusa MK2.5 with Bear Upgrade 2.0

This is a remix of the Y-axis idler mount for a Bear 2.0 upgraded Prusa MK2.5 to make it compatible with the Gates idlers sold by E3D. (Bear Upgrade 2.1 includes an official (optional) part for these upgraded idlers.)

I based my modification off of the changes motocoder made to his remix of the MK3 version to accommodate the same idlers. You'll need some 5mm (4.5mm might be better) rod to use as an axle due to the larger bore on these idlers. I had some 5mm stainless steel dowel pins from Acklands-Grainger kicking around that were too long and a bit tight on diameter - I spun it on some some 600 grit sandpaper to reduce the diameter, cut it down to the correct length (~23mm) with a dremel tool, and it works great.
