Here is a build plate of Handheld Rayquazas done in Hueforge! They are sized to be keychains but can be resized on the x and y axis.

Filament used:
Sunlu Black
Polyterra Matte Green

Amolen Bamboo

(I know I messed up the red part which I decided to do with acrylic, I'm sure you can do better if you decide to add any paint!
