Greefa printer rewinder reel block

I rebuilt the block by improving the pin fixings with the integration of the nut so as to facilitate installation without using wrenches, I added a figure to the tightening of the ring because the plastic thread was stripped after so many years, I reinforced the original design so as to avoid breakage.

the drawing will be updated with the modification for the reel extractor so as to facilitate its extraction
