Chair Caster Support

This is a replacement caster support for the Mac Tools Mechanic's Chair. The caster support get old and brittle and eventually break allowing the wheels to fall out. The inside diameter was printed a little tight to compensate for the wear on the caster shaft. The hole for the shaft may need to be drilled out to fit a caster shaft that has not much wear. Insert the caster shaft into the support the press or hammer the caster and support into bottom of the tube of the chair.
