Vase Mode Christmas Ball

This is a Christmas ball of my own design.  It's a fairly challenging print in vase mode.  I was able to print it successfully, but not on all of my printers.  It requires slow speed and very high cooling to avoid drooping in the overhangs.  I have a Sanyo-Denki 4028 fan for part cooling on my RatRig VCore 3 and I had to run this at 65% to get a good quality print.  It printed well on my Mk3s+ until it got to the overhangs where the part cooling couldn't keep up.  If you have upgraded your part cooling, it should print well, just go slow (20-30 mm/s).  I'd also suggest using a brim for bed adhesion, and printing the first 8-10 layers solid before starting vase mode.  This gave me a stable base, even with the high pressure of the air from the cooling duct.

I bought a pack of ¾" (~20mm) Christmas Ornament tops on Amazon to print some other designed on Printables, so I designed this ornament around that same size top.
