What's new and what's up:
As it turns out I only have less than a month to "finish" it, so here we go!
The first version was based on proper hardware, so you'd need drills, workbench, saws, etc. This time, I decided to make everything 3D printed. It's a lot more customizable and there will be almost no chance for somebody to lose a finger.
All documentation and pictures are from old project. I will start modelling everything as soon as I get the components I need, so sit tight!
