DIY Tilt Sensor

I used this for another project, and I wanted a told sensor without having to purchase a bunch that I may never use.
I modeled the holes but it is difficult to get correctly sized small holes so I used them mainly as a guide to drill holes.
I used a 6x3mm Neodymium magnet as the ball. I originally intended to use Aluminium foil, but found that it could be inconsistent and was prone to getting caught.

I used the following G-Code to pause the print to place the magnet inside:
G1 X50 Y200
