Threaded Easter egg

This egg was intended to be printed 15cm tall overall, with a *single wall* on a 0.6mm nozzle for a trade-off between strength and material usage. I used a 0.24 layer height.

The top part of the egg uses *0 initial bottom layers* and 3 global bottom layers. Top layers is your choice, start with 4 and work up if you have any gaps.

The top part has a custom STL support "egg support disc" if you want to use this instead of your slicer's default supports as it should be just a single trace and more economical and reliable. You can load this to your slicer as a regular model. You may have to scale the ring's Z dimension so that you're left with at least 1-2 layers of gap. The overhang begins at Z = 9.63mm. Use brim supports on both pieces.

The bottom part used 2 top & bottom layers (global), however, had a mesh modifier (a big box is fine). I use Cura and my modifier has these qualities: (1) Scale - XY >107mm, Z = 48.5mm. (2) mesh height Z = 9.6mm, elevated over build plate.
