command module

command module for syringe operated toys I liked a lot the modell uploaded by [trinityscsp], https://grabcad.com/library/excavator-with-syringes-wooden-toy-1 but watching the video on YouTube about the original build I found that the control of the movements it's to hard even for a grown-up. So I decided to draw a module for a more simple control, it can be built in a modular way to be able to combine as many as necessary for the given project. This is just a concept, the dimensions are arbitrary/random and if you check the SolidWorks modell you will find a lot of mistakes mainly in the final assambly, but it's just a concept...
