Backbone one Joystick safers

Hello,

I've adapted this model (https://www.printables.com/model/510666-joystick-savers-v2) to function with the Backbone One and it works functions flawlessly. Apologies for not separating them into two distinct files. I've successfully printed my model with a 0.6 nozzle, although a 0.4 nozzle would be even more suitable.
