Unilateral Flange Expansion

My GT2 timing belt was climbing off the unilateral flanges (I'm not to sure what the correct term is - top roller for the GT2 belt on my Kossel). This caused failure of the belt and it caused the print to fail.

I decided that I was going to lift the roller wall by printing higher "walls" to prevent this. The parts fit loosely around the unilateral flanges so I had to glue it into place with super glue.

The end result works wonderfully and I now have the confidence to do a large print unattended.
