After much wringing of hands and banging of head I decided to assemble useful calculations for gear design into one script. All of this is based upon http://www.thingiverse.com/thing:3575 and includes the spur gear fitting function from http://www.thingiverse.com/thing:6894.


If you want to do fancy things with useful gears in OpenSCAD, use this and have fun.

So, how's the millions rolling in from the design you pulled so they wouldn't "steal"?

Stratasys is the only one making millions. If you really enjoy what open-source hardware and software allow you to do, then maybe you should park the condescension and take action to protect it. Sheeple get what they deserve.

...and what have you done to protect it? Or have you just protected yourself?

Publishing something then recoiling at the threat someone might actually use it isn't very "open". Opening a design means needing to accept that it could be used in things you don't approve of or by people you don't approve of.

I'll give you the benefit of the doubt and assume you are unaware of Makerbot's actions:
The only protection I want for the things I create is that they remain freely available in the public domain and not usurped by someone who then claims exclusive rights for their use. I refuse to support organizations, like Makerbot/Stratasys who engage in this behavior by using their "free" services. Their services aren't free and their actions are dishonorable.
You're welcome to peruse my and my colleague's contributions to the community in a location not associated with greedy corporations:
Stop being a troll and a tool.

My point is, closing your designs does not inconvenience Makerbot in any way, just hurts the people you want to convince.
Thank you for the links. Them being available in some other way mostly defuses my argument. You haven't closed it, just moved it elsewhere.

You going elsewhere for your designs and refusing to participate in this sham they call thingiverse does hurt them.
If no one makes a stand, demonstrates some displeasure at disgusting behavior, then the conclusion is that everyone condones said behavior, it becomes the norm, and we user/contributors are ultimately the ones who lose. If you're satisfied with the status-quo, then do nothing, but be big enough to let me register my disgust at what Makerbot/Stratasys have done the way I wish to.
In the mean time, go print something and have some fun.

You keep saying so, I don't see any reason to assume so. I may well find other grounds hearing about this patent business, but razing my account here to the ground would only hurt me. At the very least I'd leave redirects instead of giving my subscribers a manifesto and uplifted finger.

So your argument ultimately comes down to benefiting yourself ("...razing my account here to the ground would only hurt me.") which is precisely why you're supporting MakerBot and Stratasys - you're like-minded. The well being of open-source communities is what drives my actions and doing nothing in the face of injustice like this isn't my nature.

You left out two big important part of my argument.
1) It helps nobody.
2) It doesn't hurt anything you actually want to fight.
3) It DOES hurt YOU.
So -- it's pointless, self-destructive, and yes, childish to raze your account to the ground and not even leave links.

Trying to reason with someone incapable of counting is clearly a waste of my time.
Knock yourself out being a sheep - you're sure to enjoy the rewards.

You are at the very least equally blind... I've conceded some of your points and am leaving them because of this. Not because you razed your account to the ground and left no links -- that is stupid -- but because you were willing to talk and explain.
But sure. Enjoy your pointless self-aggrandizing ragequit. It fits the pattern.

So... You're afraid they're going to patent your gears?

is this a perfect internal gear or have you only subtract the normal gear from a cylinder?
