Ordered marble filament specifically for this print and I couldn't be happier with that choice. Printed three of them from the spool. Printed the key from ABS and painted it gold.
wow love the filament what brand is it
"AMOLEN 3D Printer Filament, Marble Color 1.75mm PLA Filament" on Amazon. Little pricey and looks like cookies and cream in pictures there, but looks great in person.
