All cut parts are placed on the print bed just as we would print them, saving you time.

Feel free to scale the model to fit your needs. Learn more about sizing and scaling for cosplay here.

🖨️ Printer Settings

• Layer height: 0.15 mm

• Infill: 10% gyroid pattern

• Supports: 30° organic

• For taller parts, use a brim for better bed adhesion

Settings may vary depending on your printer, so treat these as a starting point.

🛠️ Assembly
Glue the parts together - hex pegs are included for easy alignment. You can fuse the seams using a soldering tool.
To assemble the opening mechanism, connect the joint and secure the jaws together with a rubber cord. ( I used a spring, which is stronger, but less comfortable.)
Finally, attach a thick, flat rubber cord to the sides of the mask using superglue to serve as the strap for wearing the mask.
