As you can see it's been a while since I posted about this project. Despite what you might think ; I have not abandoned the built, but I have been too busy with other things.
Recently I started a basic course on 3D designing, and as a matter of fact, I have been using this very model to tinker with designing in Tinkercad.
Here you can see what I have so far, and if you have access to a 3D printer, you can even download the parts
