Parametric Spur Gear

Utilizing an impressive design found at: https://www.thingiverse.com/thing:3336641, I've revamped the entire spur gear mechanism to enhance customization capabilities. By implementing a copy-new paste method in Fusion360, users can effortlessly generate multiple custom gears. A new parameter set is automatically generated for each new gear. I consolidated all parameters into a "vars" sketch, streamlining the original design by reducing the required parameter count. Here's a summary of the parameters:

* g_module: Determines the pitch of the gears, specified by the user.
* g_teeth_count: Specifies the number of teeth on the gear, as per user preference.
* g_height: User-defined height of the gear.
* g_hole_diameter: Diameter of the gear hole, adjustable by the user.
* g_tooth_scale: Allows for tooth scaling to accommodate processing margins, with a minimum value of 0.6.
* g_pressure_angle: Determines the pressure angle of the gear mechanism.
