Gears (with a twist)

This is a minor customization of the gears library for OpenScad.
It allows printing of worm gears horizontally (for anyone who is interested...)
I came up with this idea after printing a worm gear vertically. Although the print quality was amazing, as the gear grew taller it started wobbling and I had to stop the print halfway.
Trying with different kinds of brim, skirt, raft did not help a lot, especially for longer (higher) gears. So I thought I should try to print horizontally. Now, I know any slicer can rotate the part by a specific angle around any axis but I just had to add this functionality to an already perfect customizer menu.
There is a new option under the worm parameters section, a checkbox that - when checked - creates the worm gear horizontally instead of vertically.
Well, this is it and thanks for bearing with me!
