CTC prusa i3 x axis bearing tension idler

*** EDIT***
I lost 20mm print space on my right hand side due to this upgrade but I;m getting some smaller flanged bearings im going to re model this part for so I will upload the updated version asoon as I get the bearings and make the model. its still going to have the 8mm plugs to hold the bearings im going to make the tensioner smaller and get rid of the discs at the sides of the bearings

*** EDIT ***
I've added a new part it uses the 608 bearing still but this is smaller and give you
