HP DirectJet 500 Roll Spindle C7769-60242

I bought a hp directjet 500 and it didn't come with the spindle, The inner diameter of the spindle is 3/4" so you can use a 3/4" wooden dowel and slide both of these on. The Roll end cap should be stationary at the end of the rod, and the other one is slightly larger and should slide to fit the paper roll.
