The hidden per-download fee
MyMiniFactory's 10–15% commission is well-known. What's less visible is the additional per-download library fee — approximately $0.49–0.89 charged on top of every paid download. For a $3 mini STL, a $0.69 fee is nearly 25% of the sale price, on top of the commission.
Low-priced model packs — common in the miniature community — are hit hardest by flat per-download fees. A $2 pack loses a disproportionate share to platform fees compared to a $15 pack.
How HiddenMark Stops MMF Pack Leaks
The miniature STL community has a well-documented piracy problem. Paid model packs spread through Discord servers and Telegram groups within hours of purchase. Creators lose sales they'll never know about, and the leaker is never identified.
MyMiniFactory has no technical response to this. Proofly's HiddenMark system embeds a unique steganographic code per buyer inside the mesh geometry of every paid download. The code survives reslicing in PrusaSlicer or Chitubox because it lives in the vertex data, not in file metadata.
When a pack surfaces on a piracy channel, upload one of the files to proofly.store/hiddenmark — the system identifies exactly which buyer it came from. You go from «my models are being shared for free» to «buyer #347 leaked it» in seconds.
🔐 HiddenMark™
Per-buyer fingerprinting on every paid download. No extra steps — it happens automatically at the moment of purchase.
How HiddenMark works →You don't have to choose
MyMiniFactory has a large existing community that's hard to leave overnight. Proofly doesn't require you to. No exclusivity requirement means you can cross-list your catalog on both platforms simultaneously — keep your MMF presence for existing followers while using Proofly to reach buyers who expect a 3D preview before purchasing and want their download protected from sharing.
Any model uploaded to Proofly earns 0% platform commission from day one. Upload takes about 2 minutes, the 3D viewer is automatic, and HiddenMark protection activates on every paid download with no configuration.
