List of componets, source and specification

One should very much clear what he needs to design the electronic hardware. Some parts are 3D printed here and can be downloaded its .STL file from link that is given and also can be converted into G-code using Repetier-Host. But alternative for those 3d printed parts is to design them from wood or foam.
