  • WORD OF MOUTH: Invite your friends to come, discover the platform and the magnificent 3D files shared by the community!

Sharing and ing on Cults3D guarantees that designs remain in makers community hands! And not in the hands of the 3D printing or software giants who own the competing platforms and exploit the designs for their own commercial interests.

Cults3D is an independent, self-financed site that is not able to any investor or brand. Almost all of the site’s revenues are paid back to the platform’s makers. The content published on the site serves only the interests of its authors and not those of 3D printer brands who also wish to control the 3D modeling market.
