With a bit of hacking the code you can have it do whatever you want, such as bevel gears, helical gears, and so on, and with a zero height, output a 2D file as a DXF. * Sample for gear and grub. No gear slippage but the door doesn't open all the way because the bar is in the way. Using this software, you can design helical gears (with specified helix angle), V-shaped helical gears, and spur gears.It lets you design gears with teeth on internal or external circumference. An openscad script that does helical gears also. However, a helix angle of less than 10° has hardly any advantages over straight teeth.
