Serpiente GBC
This is designed originally by FernandoQ. Dunes, Berthil, and NDL-GBC have each made their own versions of it, this being a mash-up of all their designs. Dunes made mods to the stepper, removing some funkiness Fernando did with the frame to keep it from colliding with the serpentine. Berthil made a new structure for the serpentine itself, which he has used on Logarithmic Ball Counter and Snake Circle. NDL made the mods to the gearbox, changing it from a 3:1 ratio to a 5:1. A nice, long Akiyuki snake slide is used to get the balls back down to normal height for the next module. I have also improved how the snake slide is attached at the bottom, using a technic connector rather than having a liftarm attach to exposed studs. This module is good to have as a spare to throw in the loop if a big module fails. It is also good for testing modules, with the snake slide wrapping around the back of the module being tested.
