About this 3D model

I tried to print 50mm canon lens hood by oldhui ( https://www.thingiverse.com/thing:3298377 ) but after that, I had a lot of problems with removing the supports. So I redesigned his model to avoid using supports. Now the hood is working nicely just after the print without extra work. Source files attached!
