The 30% commission problem
Gambody built a well-known home for game-inspired 3D models — but at a steep cost: roughly 30% of every sale goes to the platform. On $500 of monthly revenue, that's $150 gone before you see a dollar. At $2,000 per month, you're handing over $600 every single month, year after year.
Proofly takes a different approach. Sellers list for free and keep 100% of their listed price. The platform earns only from a small flat fee added at checkout for the buyer — not a percentage skimmed from creators.

More formats, more buyers
Gambody is STL-first. That works fine for FDM printers, but it leaves resin printers, digital hobbyists, and buyers who need GLB or OBJ for rendering without an option.
Proofly supports STL, GLB, OBJ, 3MF, FBX, and ZIP bundle packages in a single listing. You can bundle a pre-supported STL, an unsupported OBJ, and a readme all sold together. The in-browser 3D viewer renders every format without a plugin.
Trace piracy back to the exact purchase
Gambody has no mechanism to trace a file after it leaks. Once a buyer shares your STL on a piracy forum or Discord server, you have no forensic trail.
Proofly's HiddenMark system embeds a unique steganographic code into every download — a different code per buyer, per purchase — inside the mesh geometry itself, not stripped metadata. If your file surfaces anywhere, upload it to proofly.store/hiddenmark and you'll see exactly which purchase it came from.
🔐 HiddenMark™
Every paid download on Proofly is automatically fingerprinted — no extra steps. It happens at purchase time, transparently, on every format including ZIP bundles.
How HiddenMark works →You don't have to leave Gambody
Proofly has no exclusivity clause. If you have an existing Gambody catalog, cross-list on Proofly without removing anything. Many creators keep Gambody for its existing audience while using Proofly as their zero-commission storefront for new buyers.
Uploading a model takes about 2 minutes. The 3D viewer is automatic — upload the file and Proofly generates the interactive viewer. No extra configuration needed.
Frequently asked questions
Is Proofly really free to sell on?
Yes. Proofly charges sellers 0% commission. There are no listing fees, no monthly plans, and no percentage taken from your revenue. The platform earns a small flat fee paid by the buyer — nothing is deducted from you.
Can I sell game STL models on Proofly?
Yes. Proofly supports STL, GLB, OBJ, 3MF, FBX, and ZIP packages — all common formats for game-inspired and tabletop miniature models. The marketplace is built for 3D printing and includes an in-browser viewer so buyers can inspect geometry before purchasing.
Does Proofly support all file formats?
Proofly supports STL, GLB, OBJ, 3MF, FBX, and ZIP bundle packages — far more than Gambody's STL-focused library. You can sell multi-format bundles in a single listing so buyers get every variant in one purchase.
What is HiddenMark and how does it protect my models?
HiddenMark is Proofly's steganographic watermarking system. Every download gets a unique invisible fingerprint embedded inside the mesh geometry — not in metadata, which can be stripped. If your file leaks on a piracy site or Discord server, upload it to proofly.store/hiddenmark to identify exactly which purchase it came from.
