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.
