I dropped my platinum 3776 a while ago, and the finial shattered. By gluing the parts back together I was able to get some rough measurements and make this replacement part. Ideally, it would be printed in clear resin, but I don't have access to a resin printer to test this. Hopefully, this saves at least one other person some time.

Note: The product was dimensioned in Inches. You will need to let your slicer scale the part to print properly.
