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 3D print 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
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.
