As we took on the littleBits Instructable Build Night with some of the littleBits projects (many which were done with our Kid's Open Make group), we noticed that the parts would sometimes slip as they were being moved around and tested out. When this happened, the connection to each module would obviously be severed. Thus, the idea for individual clips was born.

Step 1: Tools and Materials

Tools needed:

- 3D Printer (any type will do)

- Digital Calipers

*Note: We realize not everyone will have a 3D printer but as this Instructable Build night was done at the Tampa Hackerspace, we had access to this equipment. We hope you too might have a space like this near you!*

Step 2: Measuring Time - Rectangle Wrap and Snap Clips

Rectangle Wrap

Time to use the Digital Calipers. Go ahead and connect 2 of the littleBits together. It really doesn't matter which ones as they are all uniform in size. Now take a measurement of the rectangle that is formed by the pieces being connected side by side. Once you have the length and the width of the rectangle, you will also want to think about how thick you want to make it. Attached you will find our STL files for the 3D printer. We did a few sizes as some 3D printers act differently.

The wrap_strap files attached are the full rectangle STL.

Snap Clips

If you would rather try it with the snap clips, this time you will take a measurement of the height and width formed by the pieces being connected side by side or you can still just do the width and figure out the best size for you on the length. Once you have the measurement, again you will also want to think about how thick you want to make it. Attached you will find our STL files for the 3D printer. We did a few sizes as some 3D printers act differently.

The snap files attached are for the snap style clip STL

Step 3: It's Printing Time

Using the STL files we attached (or perhaps you have used another CAD program to do your own) you are ready to print. Just let the 3D printer now do the work and when it's complete, test it out. You may find you might have to do work with the piece a little (maybe an acetone vapor bath or the like) to get them to fit just snug.

That's it! Hopefully you will find them as useful as we have here at the Tampa Hackerspace!

<p>They now make brick adapters that work with LEGO Bricks <a href="http://littlebits.cc/accessories/brick-adapter" rel="nofollow">http://littlebits.cc/accessories/brick-adapter </a> and <br>Mounting Boards http://littlebits.cc/accessories/mounting-board that allow the littleBits to be attached. The first time your bits are snapped onto the mounting board may take a few tries to get them to stay, so they aren't 100% perfect.<br></p>
<p>Could design something in V Carve Pro and cut it out of plastic... </p>
<p>Very true. Especially if you have access to a small CNC machine (we have a Shapeoko 2 at the space).</p>
<p>Um yeah we just use rubber bands for hair and wrap those on. Im just saying is all. Please don't hate me for my attitusde</p>
<p>Cool, that works too. Necessity is the mother of invention, no?</p>
Nice! I have littleBits and I also thought they needed more than just magnets to connect.
