# 921 Leong Chen Chit’s 20 Intersecting Cubes

When I first saw this modular, it broke my brain, but knew I wanted to fold it. I looked and looked for instructions and finally reached out to Leong Chen Chit, through connections to Sydney Origami Group on fakebook:

Units for this model are folded from an ‘almost’ half a4 sheet, through an ingenious geometric construction you get a fan fold that can then be mutated into the basic unit.

Construction was … well … baffling. It took me many attempts before I finally “got” how the units interrelate and master the locking mechanism. The units when combined gently curve eventually becomes spheric.

I like this a lot, and will re-fold it without the construction lines so it is cleaner. I thank Leong for the opportunity to fold this model, and once again praise that thing that is the Internet, for connecting a noob (me) to a master.

I could kiss you! I’ve been looking for the crease pattern for this piece for months! Your post has given me just enough hints at how to make this while still leaving it a wonderful puzzle to figure out thankyou!

Thanks for this—I was looking for a pattern for this model. Thanks to you I was able to figure it out. For anyone interested, I’ve calculated the proportions of the paper to be (the square root of 5) x 6—or to a very close approximation, 5.6 x 15. (Using centimeters, this is a good size)

…or 13.4 x 5, makes it possible to get three pieces from a 15 x 15cm square.

Sorry to anyone who cares…it was very late when I posted the above and my brain was not working. The proportions for that paper should be 2 x 3√3, which makes 5 x 13cm an even closer approximation.

Hey, its a beautiful geometric piece. Would love to try making it.
Could you help me with instructions, if you have any?:)

1. I contacted Leong directly through Facebook and he gave me the instructions (and asked me not to share them) – you could ask directly also?
