Chefosaurus Rex & Pyro Dino – Once Human Fan Art

Bring your favorite mutated dino from Once Human into the real world!

This is my fan-made take on the Chefosaurus Rex (green) and Pyro Dino (fiery red).

Both versions are included in the same STL - it's up to you how you want to paint it.

The model is split into 5 parts for easier printing and painting: body, head, horns, arms, and tail.

It's full of detail and prints beautifully even at small scale.

I made this as a personal tribute to the weird and wonderful world of Once Human.

This is not an official model, and I’m not affiliated with the creators of the game.

All rights to the characters belong to their respective owners.

This is just fan art made for fun and for personal use only.

Default size is about 11 cm, but feel free to scale it up as much as your printer can handle.

The detail holds up great even at larger sizes.

Hope you enjoy printing it as much as I enjoyed sculpting it!
