Summary

I halved the original file and enlarged each one to 450%.

Print Settings

Printer Brand:

Creality

Printer:

Ender-5 Plus

Resolution:

0.2

Infill:

10% Cubic

Filament: Sunlu PLA+ Burly Wood

Notes:

Printed with tree supports everywhere and after printing the left hand side I used support blockers to reduce the number of trees!
LHS was supposed to take 24 hours and 1 minute but was finished in 18hours and 56 minutes.
RHS was supposed to take 22 hours 8 minutes (fewer supports)and was finished in 17 hours and 27 minutes
The amount of filament used was accurate to the predicted amounts at 204g and 193g again because of fewer supports.
Anything larger than 450% would slice but not provide a preview and so I was relunctant to start a print without being able to see the supports.
I think it will print with prints only on the end spikes of each half but I haven't tried in case it is a waste filament.

To give an idea of size the egg is from Aldi and is classed as very large!

I use a micro-swiss direct drive with Revo and a sonic pad on an Ender 5+ with Creality slice 4.8.2
