X axis belt scrape fix and tensioner

This is a belt fixer and tensioner,
Are you tired of your X-axis belt scraping along your bearings?
Are you tired of other belt tensioners not fitting?
Then THIS is your solution!

Made for 8mm rods,
I used a bearing out of an old HDD read head.
But other bearings should work, if it does not then i added my sketchup file for you to remix on.
(please let thingiverse know when you remixed it from me, and please make photo's if you made one)
