Custom mechanical K'nex? Answered

With all this 3d printing now days, and some of it is being used with K'nex I'm wondering if there are more things that need to be added to the range. Now i can understand that K'nex with its target at younger folks (the highest age they list is 9+) it probably isn't feasible for them to spend the time developing some things.

And the things im talking about?
Pneumatics
More powerful motors
Custom gears (sizes, rack and pinion, worm gears)
Servos
A more dedicated robotics system
anything else i may have missed?

Just peoples thoughts on whether this is worth pursuing, perhaps even make them for sale (please don't sue me K'nex)

KNEX has a new robotics line coming out but it might be cool to make some custom parts.

Yeah i was wondering about the 3d printer, the other option is i finally get the CNC going and make moulds and get them injection molded

Yeah the selling bit is a hard point i guess, i want everyone to enjoy it but you cant just give it away. I know it couldnt be as K'nex but the patent thing i did overlook.

We've discussed this a little before. Personally, I really want some simple, custom connectors. Stuff like clean, straight 90 and 135 degree two slot connectors (like locked hinges), a cross shaped 4 slot piece (like intersecting orange connectors), and maybe something like a shorted two slot such that the second slot is where the hole normally would be on a dark grey connector. I think the problem is though that those pieces would required a little too much precision for a regular 3D printer, would require injection moulds. Also, legally, for one you couldn't sell them as "K'nex" on account of that being trademarked. Second, I don't know if there's like a patent for the way K'nex work themselves, because even if you named them something else, you could still be infringing on the design.
