// Author: @infused-kim

// Description:
// Simple mounting hole with gold rim.
//
// Parameters:
//   - outline: The width of the gold rim around the hole (Default: 0.8mm)
//   - drill: The actual size for the hole (Default 2.2mm - for m2 screws)
//   - drill_y: The height if you want an oval hole (Default: off)
