I made this to try to keep my printer running until some new pulleys and new belts arrive. The belt is wanting to run up over the edge of the bearing stack, so this should help hold it in line for a while.. Uses a M6x12 and T-Nut just like everything else. The second model has a deeper middle that extends into the extrusion. Longer model works much better. Gave me an extra week of print time.
The author marked this model as their own original creation.
