Kaiju No. 8 Mask

This is a digital 3D printable model of a Kaiju No. 8 mask with an opening jaw.

📦 Included Files

• STL (cut for 200mm printer beds)

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

📏 3D Model Dimensions

• Width: 213 mm

• Length: 197 mm

• Height: 387 mm

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.
