Pumpkin Spice PLA
I recently ordered some sample filaments off Amazon to test out. Whole rolls of Porto-Pasta are not exactly cheap, but a 50g coil will let you see what it can do before investing.
This is their cinnamon filled htpla that I've printed Melisandre's necklace in. The stone is off an other brands sample transparent red pla.
The print was thin enough to shape with a hairdryer and has held its shape since. While it did smell like cinnamon while being printed, the smell wasn't overpowering and does go away once the part is cooled.
