Sell 3D Models Online — Keep Every Dollar
Proofly takes 0% commission. Set your price in USD, PLN, or EUR — buyers pay a flat $1 platform fee on top, and you receive 100% of your asking price via Stripe. Every download is automatically watermarked so you can trace leaks. No exclusivity. No monthly fees.
What you actually keep per $15 sale
Commissions reduce your earnings on every single sale — they compound over hundreds of transactions. Here's the real per-sale comparison on a $15 model.
| Platform | Commission | You receive |
|---|---|---|
| Prooflybest | 0% | $15.00 |
| CGTrader | 30–45% | $8.25–$10.50 |
| Gumroad | 10% + fees | $13.00 |
| Etsy | 6.5% + listing | $13.52 |
| TurboSquid | 20–60% | $6.00–$12.00 |
| Cults3D | 20% | $12.00 |
| Renderosity | 30% | $10.50 |
Figures approximate. Exact amounts vary by Stripe processing country, currency, and platform membership tier.
Why 0% commission matters at scale
The commission gap looks small per transaction, but it compounds. A creator selling 200 models per month at $15 each sees:
At 200 sales/month, switching from CGTrader to Proofly adds $12,600 per year to your income — without raising prices.
How selling works on Proofly
Upload your files
Drag and drop STL, GLB, OBJ, FBX, 3MF, BLEND, or a ZIP package. Proofly auto-detects formats inside ZIPs, extracts a preview mesh, and generates 4 render angles as cover images.
Set your price and description
Enter your price in any currency. Use the AI description generator (one click) to write a keyword-rich listing. The AI pricing tool shows the market average for similar models.
Publish — your model goes live instantly
Your listing gets a 3D viewer, piracy tracing, SEO-optimized URLs, and is indexed in the marketplace. Buyers see the model rotating before they pay.
Get paid via Stripe
When a buyer completes checkout, the payment is split via Stripe Connect: your full asking price lands in your Stripe account, the $1 platform fee goes to Proofly. Your money, separate — no pooling.
Which 3D formats sell best
Best-selling niches: miniatures, props, functional parts, cosplay armor. Ensure watertight geometry — Proofly's AI upload checker flags non-manifold edges automatically.
Include PBR textures inside the GLB container. Low-poly game-ready assets with LODs are in high demand from Unity and Unreal Engine developers.
Rigged and animated FBX files command premium prices. Include bone naming conventions compatible with Unreal Engine's skeleton for maximum compatibility.
Universally compatible. Bundle with MTL and texture maps in a ZIP. Architecture and product visualization buyers prefer OBJ for its software compatibility.
Next-generation print format with metadata and multi-material support. Increasingly preferred by PrusaSlicer, Bambu Studio, and Cura users.
Bundle STL + GLB + OBJ + textures in one ZIP. Proofly extracts a preview mesh automatically. Multi-format packs justify higher prices and broader buyer appeal.
Built-in piracy tracing: HiddenMark
Every purchase on Proofly automatically stamps the buyer's download with HiddenMark — an invisible watermark embedded inside the mesh geometry. No two buyers receive the same file.
Unique per buyer
Each download contains a code linked to the specific purchase record — not just "this file is from Proofly" but "this file was sold to buyer #4821 on July 26."
Survives conversion
The watermark is embedded in vertex positions, not metadata or file headers. Re-exporting to another format, slicing, or remeshing does not remove it.
One-click verification
If your file appears on a piracy forum, upload it to proofly.store/hiddenmark. The verifier reads the code and shows exactly which purchase it came from in under a second.
Creator tools included in every account
Founding Creator programme
The first 100 creators to list on Proofly receive the Founding Creator badge permanently — it appears on every listing and their public profile forever, regardless of when a buyer sees it. Founding Creators also receive priority placement in search results and free boost credits.
Spots remaining: limited. Once 100 creators have published, the programme closes.

How much does it cost to sell 3D models on Proofly?
Listing and selling is free. There is no monthly subscription and no commission taken from your sale price. Buyers pay a flat $1 platform fee on top of your price — that fee goes entirely to Proofly and does not reduce your earnings.
Which 3D file formats can I sell?
Proofly supports STL, GLB, GLTF, OBJ, FBX, 3MF, BLEND, and ZIP packages containing multiple formats. Buyers can preview STL, GLB, OBJ, and FBX files in the interactive 3D viewer before purchasing.
How do I get paid?
Connect your Stripe account during onboarding. When a buyer completes checkout, the sale amount (your price, minus Stripe's processing fee) transfers directly to your Stripe account. You can set up automatic weekly or monthly payouts to your bank.
Can I sell the same model on multiple platforms?
Yes. Proofly has zero exclusivity requirements. You can sell the same model on CGTrader, Cults3D, Printables, or anywhere else simultaneously. Cross-list a premium multi-format version on Proofly and keep the free version on Thingiverse.
How does Proofly protect my models from piracy?
Every download is automatically stamped with HiddenMark — an invisible watermark inside the mesh geometry. Each buyer receives a uniquely coded copy. If your file is leaked, upload it to proofly.store/hiddenmark and instantly see which purchase it came from.
Do I need design software experience to upload?
No. If your file is ready to sell (watertight STL, properly exported GLB, etc.), the upload form guides you through title, description, tags, and pricing. The AI description generator writes your listing copy with one click.
