625 Xaxis bearing

I am uploading this in stead of emailing it to myself, print at you own risk i have not had the chance to print or test this yet and it might still need a lot of tweaking to get right, this is my first go at this item. With that said this is meant to replace leaner bearings on a prusa I3 the holes are lined lined up the same as the metal housed leaner bearings and i tried to mach the size as close as possible.
uploading the latest rendition of the bearing and have not printed yet to see if it will work better.
ok, after a print and test fit i found that the first and second rendition are a little large for a M8UU shaft so the third revision I have reduced the diameter and hopefully it will fit better, I will know more after i print the third Rev and test fit it.
the first two should fit a 8mm shaft the third revisions will fit a 7.7mm shaft witch is closer to the M8UU shaft my printer rides on.
