Can I buy a 3D model already made? Brian Taylor February 23, 2017 14:40 Updated Follow No. We sell only the STL files. These files can be 3D printed on any type of 3D printer. If you don’t own one, you can use the services of our partners, 3DHubs and Treatstock. Related articles Where can I see the assembly instructions for the model?
