This is a large threaded egg. It was designed to be large enough to hold one of McGybeer's articulated dragons (printed at the default size). Looks particularly good in multicolor coextruded filaments.

It will print OK without supports, but the bottom points of some of the scales get a bit messy.

Update 12/25/23: Uploaded separate top and bottom .3mf files 

Update 1/6/23: Added a revised version with a wider base, which dramatically improves the print quality of the lower layers
