This is a remix of a Deadpool keychain, modified to be printed in multiple colors using a single-extruder 3D printer with filament changes by layer.

The keychain is at its original full size, but I resized it proportionally to be 4 cm in height. After adjusting the scale, I disabled the scaling and set the layer height to 4 mm.

For the print, I used Orca Slicer with the following filament changes:

1. Layers 1-10: Printed with white filament.
2. Layers 11-15: Filament change to red.
3. Layers 16-20: Filament change to black.

These filament changes help to highlight the distinct features of the Deadpool character, resulting in a vibrant and detailed finish. This keychain is a great addition for any Deadpool fan, and it's easy to print on a single-extruder printer using this technique.
