The Math Free3D Doesn't Show You
If your Free3D model has 5,000 downloads, that's 5,000 people who wanted your work. Here's what those downloads are worth with a price:
* Keep your free version on Free3D for discovery. Sell a premium version (pre-supported, multi-scale, or with commercial license) on Proofly. Zero exclusivity — cross-list both simultaneously.

What Proofly Does That Free3D Can't
In-Browser 3D Viewer
Buyers orbit, zoom, and inspect every vertex of your mesh before purchasing. STL, GLB, and OBJ render in WebGL — no slicer required. Reduces "not what I expected" complaints to near zero.
HiddenMark™ Piracy Tracing
Each buyer gets a unique invisible fingerprint baked into their file's mesh geometry — undetectable in slicers. If your file leaks on Discord or a piracy site, upload it to proofly.store/hiddenmark to identify the exact buyer and order in seconds.
0% Commission, Always
Proofly earns only from a small flat buyer fee (~$1 / ≈4 PLN). You list at $3 — you get $3. List at $50 — you get $50. No percentage skimmed, no tiers, no surprises. Stripe Connect pays out directly to your bank account.
20 Currencies, Global Buyers
Buyers see prices in their local currency (USD, EUR, GBP, JPY, and 16 more), converted automatically. You set one price; the marketplace handles the rest. Reaches buyers who never use USD-only platforms.
The Dual-Distribution Strategy
You don't need to leave Free3D. The smartest approach is to run both simultaneously:
Frequently Asked Questions
How much do Free3D creators earn per download?
Free3D.com offers free downloads only — creators earn $0 per download. The platform has a paid tier for premium models, but it takes a percentage of each sale. Proofly charges sellers 0% commission: buyers pay a small flat fee (~$1), and the creator keeps 100% of their listed price.
Can I sell the same models I upload to Free3D?
Yes. There is no exclusivity requirement. You can keep free versions on Free3D for discovery and community, and sell premium or pre-supported versions on Proofly. Zero-commission pricing means even a $3–5 listing price is profitable from day one.
Does Proofly have a 3D viewer like Free3D?
Yes. Proofly has a full in-browser WebGL 3D viewer for STL, GLB, and OBJ files — buyers can orbit, zoom, and inspect the mesh before purchasing. Free3D shows static thumbnails on most listings. The Proofly viewer builds buyer confidence and reduces 'not what I expected' complaints.
How does Proofly protect my models from piracy?
HiddenMark™ embeds a unique steganographic fingerprint into each buyer's downloaded file — encoded into vertex geometry, invisible in slicers. If your file leaks, you upload it to proofly.store/hiddenmark to identify exactly which buyer and order it came from. Free3D has no such protection.
What file formats does Proofly support?
STL, GLB, OBJ, 3MF, FBX, STEP, and ZIP packages. The in-browser viewer works for STL, GLB, and OBJ. All formats support HiddenMark watermarking. Multi-file ZIP packages are supported for complete print kits with multiple parts.
