30 Minutes for collapsing the base?! :shock:
Wow, you have to be a lot better than I expected. Yesterday I sat down to fold the cp you posted above and didn´t get the base collapsed in about three hours, no idea if I will try it again, the nearly finished base is allready lying on my desk, but I got really frustrated with it. That reminds me again on what a bad folder I am :(

I find that it is quite easy to understant why and how wolf has done what he has done. But when I try my own example it all seems alien again

hi wolf, i notice something in your crease pattern.
May i suggest something about the flap orientation of the head?
i think the head subunit should be rotated 90degrees because of the centerline of the model.
In your subunit,the flap is orientated in such a way that there are 4 middle flaps(2 large,2 small) and 2 more flaps on either side of the line of symmetry.
But in the griever model, there are 4 horns on each side (3 small and 1 big)
so i think rotating the subunit like this will solve the problem. what you (and others) think?

sorry wolf i interpreted your cp wrongly
i just realise after i read the text again.initially i was comparing the head subunit with the tree and found out that the subunit is not compatible

origami_8 wrote:...base collapsing difficulties...

I modified the square packing and CP slightly so that it'll be easier to collapse (just plonked in a few more squares in the mane area).

For box pleated CPs, there's a relatively easy way of collapsing them. First, precrease the grid and put in all the diagonals for each square. Then, identify the line of symmetry (book symmetry, in this case). Once you have this, fold a series of waterbomb bases whose tips lie along this symmetry line. Here's what the creases would look like:

Image

You'll end up with a chain of waterbomb bases of various heights and widths. Do a series of in-out open sinks along the grid lines parallel to the square's symmetry line (the vertical lines, in this case). Finally, do a series of Elias stretches to form the edge flaps, and 'pop' the interior squares into place. At some places, the Elias stretches and 'popping' need to be done simultaneously. The base will not fold flat until the interior squares have been collapsed.

The images were done in CadStd (google for it).

A standard screen capture and a graphics program.

You just need a big enough screen resolution :-)
So long and keep folding ^_^

Another submission for the D20 challenge although the credits for this model go to Wolf. It's supposed to be a Xill. Folded from 25cm x 25cm of Japanese foil.

Image

Wolf had a posting about 4-armed creatures in here blog and I was about to start folding the Rahu, when I came across the picture for this Xill, which happens to have 4 arms as well, so I went for this model instead with a very tiny variation of the Rahu-CP.

I'm quite fond of the facial expressions I managed to give this model, although it probably does not show that well on this picture:
Image

Without its weapons it does not like quite as dangerous, but with a few grafts it should be possible to add those as well (with colour change of course). Anyone wants to try that? ;-)
So long and keep folding ^_^

humm I have a wonderful model of a Beholder... okay to those uneducated in the way's of origami and make-do D&D minature replacements of the 80's it may in fact look like a crumpled ball of paper but I assure you it is an entirely original design and every one is unique!
