I am using a hanging filament spool holder to have less weight on the gantry to reduce vibration, and I need a sensor console. The ones I have found were a bit tight for the small screw, so I have built one from scratch in tinkercad. 

To use this model, there is no need to replace any of the existing screws, it can be fitted with the factory ones, once you removed the spool holder from the top of the gantry.
