Bearing belt guard for reprappro mendel

The original belt guides for the Y belt kept breaking for me so I made this quick n dirty, but sturdier version. Just loosen the nut, push the guard on the M8 and tighten the nut again. It became a bit too large but works fine.
Half a broken original guard can be seen in the photo. Note: the photo only has one of the guards in place, the other is in the printer.
