3D Models for 3D Printing — Free STL Files (MIT Licensed)

A free, open-source collection of 3D printable models in STL, 3MF, and Blender (.blend) source formats. Every model in this repository is released under the permissive MIT License — free to download, print, modify, remix, and use commercially.

Models are designed and sliced for the Creality Ender-3 (most include ready-to-print .gcode), but the STL files print on any FDM 3D printer.

Keywords: free 3D printing models · STL files · 3MF files · Blender models · Ender-3 gcode · cookie cutters · functional prints · household 3D prints · MIT licensed 3D models

🖨️ How to Use

1. Download the .stl (or .3mf) file for the model you want.
2. Slice it in your slicer (Cura, PrusaSlicer, etc.). Ender-3 users can often use the included .gcode directly.
3. Print on any FDM 3D printer.
4. Edit — open the .blend source files in Blender to customize a model.

File Formats

• .stl — ready-to-slice mesh (universal).
• .3mf — modern mesh format with print metadata.
• .blend — editable Blender source.
• .gcode — pre-sliced for Creality Ender-3.
