Umulius Rectangulum

Hi Everyone,

This looks so simple but I am simply not able to fold it....is there an easy method? I am talking about fig.3 where the unit actually comes into shape. I am almost ripping the paper trying to make it. Please help. Here's the link:

Thanks in advance,

Thanks Daydreamer....that was really so easy! And I am sorry for opening a new topic on this one...but I searched for 'Umulius' and did not find any topics, I guess i should have also searched for 'magic rings'!

The magic rings is quite a nice model. Here's a nice variation from Tjips in Flickr:

I must agree... This has to be my favorite model... I too had a bit of trouble with figure 3, but after awhile I managed to figure it out

It's very fun to try different color combinations

Ok this is probably ridiculous, but I've cut my A4 paper in half, and I CANNOT get it even split into 5 parts. It's 4.25 inches I know, but I just cannot find the right length for each section. Any help

(I don't see how it's 5 inches, I cut it hot dog style like he pretty much explained, it's 4.25 in.)

Hmm... it is hard to divide something into five, but I'd say the best way is using math... of course, you won't be using full numbers...

This is origami, you can let your calculator aside. Check how to do odd (3, 5, 7) paper divisions at http://www.papercrane.org/?a=43

Well the good news, I got it all done

Looks nice, I just guessed at the step where it said to fold the sides in (it said 1 and 5 below the paper, Im guessing 1 and 5 inches, but 5 inches was not possible , so I just guessed) so it turned out a little edgy. But it still looks nice. Thanks for helping me with dividing into 5th's

Actually the "1" and "5" are only units in general (not inch, centimeter, light years, Ã…ngstrÃ¶m, or any other measures of length) the size of one unit depending on the size of paper you are using....
1 unit = 1/5 of the width of the paper

Oh! Alright

Thanks for clearing that up Daydreamer. I would have never figured that out. But yeah, it makes sense now that I know.

I tried to make one of these this weekend, with limited success. Step 3 didn't work out, maybe it was the weight of the paper I was using.

Is there some trick to getting these two pieces to merge without warping or bending? I can tell from pictures posted elsewhere that the small end needs to fit inside the large end and the large end needs to slide all the way into the corner.

I have folded this model several times and I have never had any trouble with the caliber of the paper I used. Maybe you need to make sure you fold the ends in a way that they have the exact size and shape so that when they are introduced into that second end, they don't damage it.

The links at the papercrane website are dead. Is there any other place to find them? Thanks!
