This is a component of the Free Universal Construction Kit, a collection of adapter bricks that enable complete interoperability between a wide range of popular children’s construction toys. By allowing any piece to join to any other, the Kit encourages totally new forms of play across otherwise closed systems. As with other grassroots interoperability remedies, the Free Universal Construction Kit implements proprietary protocols in order to provide a public service unmet, or unmeetable, by corporate interests.

This piece is the Universal Adapter Brick, which provides interconnectivity between all of the supported systems.

Complete information about the Free Universal Construction Kit can be found at http://fffff.at/free-universal-construction-kit.

Please note, units are inches for all components of the Free Universal Construction Kit.

I love your conversion parts, and this is the one to rule them all. :D

This "THING" is Fucking Useless and I dont ever use any form of LEGO and this is fucking useless and impossible to print anyways


This idea and Thing are amazingly cool. Great work.

Hi, does this provide a connector from K'Nex to Lego Mindstorms NXT? (I think, but I'm not certain, that NXT uses Lego Technic parts).

I'm curious... I count 2 patented designs on that thing (and I mean ones with still valid patents).

Given that you mention on your website that you have left out 2 still-patented connectors am I just getting it wrong?

Especially given that the legal opinion that you link to on your site specifically lists the sharing of patent infringing designs as a legal grey area.

Like I said, curious.

Thanks for asking. If you actually download the .STL file, you will note that the two connectors in question are actually "blocked out" (with little signs saying "Coming in 2016"
amp; "Coming in 2022").

This is awesome and important, but we need a better way to post.

I think having seperate "things" makes sense for "I Made One" and linking derivatives, but there really needs to be a way to make a parent thing associate with child things.

Two possible solutions to improve the current state of things. (ha!)

1) To cut down on spam complaints, have a check box to keep things from showing up as "Newest Things".

2) We need another linkage other than Derivative to associate things.
I propose a button " I made a related thing!".

A Ct
hulhu Chesspiece could be a "derivative" of a regular chess piece, but a Shoggoth chesspiece designed by someone else would be a "related thing".

What.. no adapters for Construx??? There goes my childhood dreams. And no Iphone to lego adapter? Being old sucks too. :-P

It's insane enough to be considered art, I think.

I agree with the other posters that posting a a huge number of connectors, each as a unique 'thing', is pretty antisocial because it feels like an attempt to grab a lot of attention. There are lots of things with many files, such as chess sets, complex models, etc.. I don't think anyone would have complained about one huge 'thing' with all of the connectors on it.

That being said, I'd also say that given the recent flood of postings to Thingiverse, from the various contests, etc., that perhaps the site needs to be redesigned to work better with large numbers of postings. I used to check 'latest things' every day to see what people have been doing, and now I
have to check several times a day just to keep up. I wouldn't want to slow down the rate of posting, because creativity is to be encouraged. But perhaps the site could use more compact formats for some of the lists, and reserve the big graphics for the most popular list (for example)? I wouldn't mi
nd seeing the 'most recent items' and 'most recent derivatives' as text lists, for example, reserving the graphics for 'most popular' and 'who's making what', and even they could be smaller.

Not wanting to be a party pooper like the rest (but I agree, 1 thing with multiple files would have been better)

I say, this thing is awesome. Especially this thing, with everything on it. And I feel like I should print it, just for it's sheer insanity.

Have to agree with the other coments. I was amazed after posting my latest thing, to find it sunk with out trace in mere seconds by a tidal wave of spam items. Love the project but a kit posting would have been more respecting of the community.

I like but I agree with the others, why not upload everything as a single "thing" ? It would be simpler to find again later... (and would have been much simpler to post)

Forget Einstein and Hawking... HERE is the unified theory of all things! 8-)

Man, this would fall under spam in my book ...

Wouldn't it be much more logic to just place all these UCK blocks in one thing? They are all basically the same anyway ..

Also, descriptive names really help , nobody here is searching for uck00f07m, they are searching for 'connect duplo to tinkertoys' or something

Anyway, please spam less :(

Dear Thingiverse friends,

We acknowledge the complaint some of you have expressed, that the various pieces of the Kit should be combined into one Thing. We disagree; the Kit is an inherently non-finite, extensible system (which could yet include adapters for additional construction toys someday soon), and this seemed the b
est way to go. The combined Kit STLs are already 85MB, and, as you can see, still growing.

We do regret and apologize for the inconvenience caused to those of you who, though our mass-publication of the Kit pieces, missed your "moment in the sun" on the Newest Thing pages. We'd like to assure you t
hat we are not spammers and have no intention of doing something like that on a regular, or even infrequent, basis.

You could always do both - leave them separate, but have one super thing, that includes all files, and lists all the individual things as parents...

I'm with you. Is there any logical reason why these things can't be placed in one entry. I imagine it would have saved the poster considerable time.

I understand I shouldn't be looking at the newest things stream as being particularly useful, but when I see it shotgunned like this I can't help but think there's got to be a better way.
