I finally released the design files of my 3D printed tricopter. Even if the code is not so cleaned, full customization can be done thanks to OpenSCAD. This project was a way to try OpenSCAD for such design instead of traditional CAD like Solidworks and it works really well, it just took me some time to find a way to organize the code. But it allows displaying some warnings if input data does not match or automatically computes the length of carbon rods used for the arms.
