HB-20 compatible Lens Hood for Nikon 28-80mm

Short introduction
Had an old 28-80mm Nikon lens laying around which did not have a lens hood. So I decided to design one. I tried to imitate the original HB-20 as close as possible by using reference images I found on eBay.

About Tolerances
If it is too tight on you can try the "horizontal expansion" setting in Cura with a negative number. Same if it is too loose (but with a positive number this time).
Afterwards you might want too remove the strings (because of the missing supports) or shave some material off with a sharp knife to help everything fit.
