The skeleton of the frame in 3D.

Figure 1

After several days around the OpenSCAD software, the skeleton of the frame in 3D without the parts are ready. The figure 1 shows the position of carbon tubes with the final dimensions. The letters point to tubes with different lengths. The list with lengths can be found in this pdf file.

Figure 2

The figure 2 shows a top view of the skeleton of the frame. From above we can see that the frame is based on three squares.

Figura 3

The figure 3 shows a side view of the skeleton of the frame. In this figure we can see the tubes that will serve as the "landing gear".

As can be seen by the figures the frame is very simple. The next step is to put the parts in the skeleton to get the complete frame.

Plastic parts to assemble the frame of the quadcopter.

All plastic parts to assemble the frame of the quadcopter were modeled in 3D using the software OpenSCAD. I also created a repository where I put the source code files for use with OpenSCAD and the STL (Stereolithography File) files to use for those who want to print the parts in a 3D printer. I also discovered a site that prints the parts from the STL files for a reasonable price! The list of parts with the dimensions can be found at the site Shapeways, if you search for "mobileapes". Alternatively, the list of parts can be found in this pdf file. The material selected to make the parts is the "white strong & flexible" nylon , which is the cheapest. Those who prefer may choose the "black strong & flexible" nylon, once the carbon tube is black, but this option is more expensive.
