Model Forge
Parametric CAD for 3D printing — sketch, extrude, fillet, export STL.
Free to use. By downloading you agree to the licence.
This app is in alpha — in active development, not ready to download yet.
Parametric CAD with one job: designing parts to 3D print.
Draw a sketch, extrude it into a solid, then add fillets, chamfers, and dimensional constraints — every step recorded in a feature history you can go back and edit. When the model is right, it exports a clean, watertight STL straight into your slicer.
No cloud project storage, no sign-in, no seat licence. It’s a program on your PC, and your models are files in a folder.
What it replaces
Installing on Windows
The installer is not code-signed yet, so Windows SmartScreen shows a blue “Windows protected your PC” box the first time you run it. Click More info, then Run anyway. Buying code-signing certificates is one of the things donations pay for.
The installer’s first screen offers Full install (a Start-menu entry and an Apps & features listing) or Unzip (just extracts the program folder to a location you pick — no registry changes).
Every release on GitHub lists a SHA-256 hash for each file so you can verify your download. Model Forge checks for a newer version when it starts and offers to fetch it — you always get a prompt, never a silent update.
Model Forge is in beta. Expect rough edges, and save your work often.
Feedback
A bug, an idea, or a feature you wish this app had — it goes straight to the person who builds it, and it genuinely shapes what gets built next.
