SCE8UU styled housing for Igus RJMP bearings

During replacing the Y-carriage of my Prusa i3 "acrylic" i wanted to get rid of the cheap SCE8UU bearings.
As i liked the design of the bearings i decided to make a similar housing for Igus RJMP bearings, you can use this to replace the original ones without drilling new holes ;)
Based on a drawing i found on the web - sorry, no sources known *bummer*
Included the Inventor drawing
