Chainsaw Man Denji cosplay helmet

Denji’s devil form head from Chainsaw Man, ready to be 3D printed! The design features color-divided sections, so you can print in different filaments, and no painting is needed.

The download includes:

• STL files for a 200mm print bed, with parts pre-arranged for easy printing.

• OBJ file of the uncut, assembled helmet.

• 3MF pre-supported, print-ready file

MOVABLE JAW 

• The lower jaw piece has holes for a rubber cord and snap-on hinge, making it movable. You can use any black rubber cord, but a flat one looks the best.

COSPLAY WEARABILITY
We followed the look from the anime and manga, where the front saw blade is really long and sharp. We recommend printing the blade with minimal infill and as few walls as possible. If needed, you can also add a counterweight to the back of the helmet.

This works great for photoshoots (tested), but for conventions, we recommend replacing the blade with EVA foam for more comfortable wear and safety for both you and the people around you.
