Prusa I3 Y-idler Tensioner

I have been fairly dis satisfied with many of the Y-Idler tensioners so I decided to do what any good hobbyist would do and make my own,

Ii is best printed on its side with scaffolding for the bearing retainer, I used two 625 bearings, and M3 screws, the M3 nuts should slide in fairly easily but this will place the belt level with the Y-motor mount.
