About this 3D model

This was a solution thought for some of the folks getting rib vibrations on prints from the belt being guided by a smooth pulley. I didn't want to take the machine apart. Could probably glue it on the pulley.. I tried to clasp it but I didn't measure correctly, and I don't know if that kinda clasp will work, but it would allow me to add it to a smooth idler without disassembling the belts, project file from fusion included
