Here is the Model for my Wrapped Egg in time for Easter,
the ribbon is removable to expose a hole for filling it full of sweets (or to poor them out.) :-)
all parts are printable without supports but I would suggest a Brim to help hold them to the bed.
I Printed mine in Fillamentum Nobble Blue, Luminescent Red and Rapunzel Silver
I have also added a "SuperSize" Version with tighter tolerances for if you want to scale it up around 300% like @FilamentFrenzy did. :-) Thanks for testing that pal.
0.2mm but whatever you like
I printed mine with no supports but with a 15mm Brim to help hold the parts securly to the bed.
I also would recommend printing with 3 perimeters to give some thickness, as the lower layers will act as the support for the ones above.
Do not try vase mode as it wont work due to details to the bottom of the egg
