These are a selection of vase mode Christmas ornaments I designed. They all use a ¾" or 20mm ornament top.
I'd suggest printing them with 6-8 solid bottom layers. The “Star” and “ZigZag” ornaments are challenging prints that need decent cooling and benefit from a .6 or .8mm nozzle with a larger extrusion width. Use lots of cooling on them and print them with a brim. The other ones can be printed more easily and need much less cooling. If you use less fan, you can get away with no brim. When printed on my Mk3, I still used a brim. When printed on my RatRig (CoreXY) with a stationary print bed, the brim was optional unless using a high fan.
