3D Model Details

This is a digital 3D printable model of the Merchant Mask from Slay the Spire. Available prepped for multicolor printing, or as separate parts split by color variant. Includes mask variants with or without eye holes.
I’d definitely recommend printing the version with holes - otherwise you won’t see a thing :D Add some EVA foam padding on the inside for a more comfortable fit.

📦 Included Files

  • STL (color-separated, fits 200mm printer beds) 

  • Assembled OBJ file (for easy scaling)

  • 3MF multicolor print-ready file 

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

📏 3D Model Dimensions

  • Width: 173 mm

  •  Length: 50 mm

  • Height: 241 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
The mask has slots made for a 25 mm elastic strap, so it stays snug and comfortable on your head. I’d also recommend adding a bit of foam padding inside to make it more comfortable and avoid pressure if you wear it for longer.
