How do I check a Cults3D listing that appears to copy my model?
Keep the suspected model URL, your own source reference and the specific seller claim that concerns you. Compare those facts before calling an entire Cults3D storefront a clone. A similar preview can justify a closer look, but it does not establish who made the file or what permissions were granted.
Identify the work being offered and the wording that claims authorship or permission. A public storefront reference is separate from the model listing. If you only saw a preview, don’t describe unseen files as identical.
Cults’ license explanation distinguishes licenses applying to free and paid files. Read the terms attached to the actual design. A price tag or free download does not by itself explain whether someone may redistribute the file or sell a printed object.
For your own work, connect the disputed model and seller claim to your source. Keep private source files out of a public complaint. This comparison can identify the question about authorship or permitted use; it cannot certify the seller, license or purchase.
