Introduction: How to Build a Rainbow Loom Using K'NEX

Picture of How to Build a Rainbow Loom Using K'NEX

My little sister loves her Rainbow Loom, and making bracelets and stuff on her loom. She has a box full of colored bands. I looked at her loom and it looks pretty simple so I decided to build my own loom out of K'NEX pieces. I tried making a loom out of LEGO but I didn't have enough pieces to make it work. I think K'NEX pieces work much better because the pegs have a little notch on them that holds the bands really well.

If you have KNEX pieces, you can use them to make this easy to build rubber band bracelet loom. In my video, I'll show you how to make your own loom step by step using only K'NEX pieces. You just need four different types of K'NEX pieces - that's it. If you want to make longer bracelets, you can always add more K'NEX pieces to make your loom longer. It's really simple and it works! I tested it with my sister and made a single band bracelet on our looms. My K'NEX loom works just as well as the real Rainbow Loom.

There are two videos in this Instructable: a step by step tutorial at and a demo at on how the K'NEX Rainbow Loom works.

Hope you guys like. Let me know if you make one!

Great idea! Best of all is that, after the (admittedly awesome) fad passes, you can make something else out of the K'NEX, instead of having yet another piece of plastic cluttering your space, or the landfill. Eco high five!

legochest (author)Marina L.2014-05-08

Eco high five back!

Emberlily (author)2014-05-08

JonnyBGood (author)2014-05-08

Dang beat me too it! My downfall was not knowing how to make the bracelets... Great job though!

legochest (author)JonnyBGood2014-05-08

I have a demo video if you want to know :) would love to see your version

Thank you Ert44! Hope you like the tutorial video.

emilyvanleemput (author)2014-05-07

It's a great idea to make this out of K'nex, the shape of the green rods works perfect!

Thanks emilyvanleemput! Yes, the green rods hold the bands in place really well. Good thing about K'Nex, you can make the loom as long as you need.

hunter999 (author)2014-05-07

Wow! Very nice job!! :D Detailed with depth and the video totally shows them off. Well done, this could be very useful to some! :D

legochest (author)hunter9992014-05-07

Thanks hunter999! Maybe you can build one too, it's quite easy :)
