Spur parametric gear rack (experimental)

thingiverse

Create a parametric gear rack with OpenScad by utilizing the following essential parameters: module, number of teeth, rack width, and rack bottom height. The module determines tooth height and pitch circle diameter, while the other parameters specify the rack's dimensions. The pressure angle is fixed at 20 degrees. After printing, kindly provide feedback. To generate your gear rack, use the following code: "use ; gear_rack(mod=1.25,number_of_teeth=20,rack_width=2,rack_bottom_height=3);". Upon rendering or compilation, you will receive the total length of your gear rack in mm via the echo statement: "ECHO: 'Total length of gear rack (in mm): ', 78.5398". Additionally, an HTML script helps calculate a suitable gear for your gear rack based on the module using the Parametric involute gears script: http://www.thingiverse.com/thing:3575
