Slay the Spire Silent Skull Mask

This is a digital 3D printable model of The Silent’s Mask from Slay the Spire 2 - including a belt accessory and Slay the Spire 1 mask version.

📦 Included Files

• STL (cut for 200mm printer beds)

• STL (cut for larger printers)

• Assembled OBJ file (for easy scaling)

• 3MF pre-supported, print-ready file for Prusa XL

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

Slay the Spire 1 option:

• Skull mask with cervical vertebrae (for connecting the full spine)

• Simple horns

• Single vertebra parts to build the full spine (3 versions in 4 sizes, including tail)

• Perforated visor for eyes

Slay the Spire 2 option: (in the photos)

• Perforated visor for eyes

• Skull mask without cervical vertebrae (fits better under a hood)

• Double horns

• Single vertebra part for a wearable spine belt

• Flame eyes + optional connector for LED/balloon light

The mask design is the same in both versions - the main difference is the attached vertebrae for the spine.

Glue the parts with superglue, then seal with clear spray paint. Add some darker brown weathering using watered-down acrylics. For the eyes, use simple balloon LEDs or make your own circuit. The spine belt is just held together with a cord (any kind works). Blog post about making the costume here!
