Benchy
{
The 3DBenchy is a 3D computer model specifically designed for testing the accuracy and capabilities of 3D printers. The 3DBenchy is described by its creator, Creative Tools, as "the jolly 3D printing torture-test" and was released (initially only in STL format) in April 2015, with a multi-part, multi-colour model released in July 2015.
Due to its status as a common benchmark, it is believed to be the world's most 3D printed object. The popular 3D printing website Thingiverse (where the model was originally uploaded) has the 3DBenchy marked as its most popular model of all time. The model itself is a tugboat design. In February 2025, it was moved into the public domain (CC0 License). This was due to false rumors around the Benchy remixes being removed by NTI off of Printables because of their copyright license. These false rumors caused NTI, Daniel Norée, and Paulo Kiefe to transition it into the public domain. The original license of the model (CC-BY-ND) allowed its use and distribution, but prohibited modifications and the publication of derivative works.
