Free 3D models

A picture is worth a thousand words. A 3D model tells more than a thousand pictures.


Nowadays more and more various CNC machines and 3D printers can be found in small workshops or at various DIY enthusiasts. There are many cheap machines that you can buy, and the Internet offers a number of DIY plans that you can use to make your own CNC machine and 3D printer. On pages 3D printer DIY plans and build instructions and CNC machine DIY plans and build instructions you can find some of the plans for the construction of CNC machines and 3D printers. Therefore, we decided to publish on this page 3D models and 2D drawings that are suitable for use on such machines.

We will publish 3D models and 2D profiles in formats as follow:
3D models:
-    STEP, IGES, Parasolid X_T or 3DM (Rhinoceros 3D software) extensions (Solid or surface models – NURBS) – suitable for all 3D CAD/CAM programs like NX, Catia, Solid Edge, Solid Works, Rhino3D, Master CAM, Edge CAM and similar 3D CAD/CAM programs.
-    OBJ extension (polygon mesh) –  suitable for all 3D  programs like: Blender, 3D Studio, Maya and similar.
-    STL format - suitable for 3D printing

2D profiles:
-    DWG or DXF extension (2D sketch) – suitable for all types of 2,5 Axis CNC machines, CAM programs and similar

Models given in these two formats (NURBS and Polygonal mesh) are suitable for import and editing in majority of CAD/CAM programs so you can use them as you need.

Our FREE PATTERNS category contains a large number of patterns which you can download and use for your projects on CNC machines or 3D printers. Each ZIP file contains DWG format of pattern, suitable for CNC routers. If you prefer DXF file format, download some of free 2D CAD programs that is available on our web page FREE 2D CAD SOFTWARE and convert DWG format into DXF. Dimensions of patterns in our DWG files are not adjusted to the particular purpose so that you will need to scale them to get the desired dimensions.

3D models presented here are simplified. You have to apply a few simple steps to create a final 3D model look.

1. Add a radiuses (round the edges)
2. Apply the Mirror command, if there are planar symmetry
3. If you want to resize 3D model up to desired dimensions, you have to do 1D, 2D or 3D scaling
4. Use the Pattern command if there is need for it.
5. Add draft angles
These steps have strong influence on appearance of 3D model but also on its manufacturing. It is much easier to add them by yourself than to remove them from our model if you need to change them. That’s why we decided to left those few final steps up to you.
