Notes on Parameters:

• Parameters can be edited to any value, but very small or large numbers might result in errors or clipping:
  
  diameter: The diameter of the button (for polygons, this uses Fusion's 'Inscribed Polygon' function; for square, this is the length of each side)
  tolerance: The tolerance added to the 3x2mm mounting hole
  height: The height of the button cap
  fillet: Rounds off the top of the button to minimise sharp edges or create a domed effect
  polygonFillet: Rounds off the sides of the polygons to avoid sharp edges
  domeSquishFactor: Dome only - how much the button is compressed. Lower values = more squishing
  domeDiameter: Dome only - the diameter of the sphere used to make the button (also affects the height)
