Roller for the bottom of a Print-Rite 3D printer

Was noticing some vibration in the printing table. The belt that drives the tables X axis was rubbing on 2 support bars on the bottom of the printer. After designing this roller to go between the 2 support bars for the drive belt to role on a roller on a 8-32 bolt and nut. The vibration has gone when traveling at high speeds.
I glued the two pieces together using plastic model cement.
If you have this printer or are the maker of this printer this may be something you will want to add.
