3-D Geometric Origami Post #2

Geometric Origami #2

So the next thing I decided to make was the Small Rhombicuboctahedron designed by Rona Gurkewitz. This module is definitely more difficult than the previous one I built as the Rhombicuboctahedron required much more time and patience. The process of folding and arranging the module wasn't as cleanly done as the book instructs but the end result is alright. Again like last time i'm going to walk you guys through the steps of creating the module.

Step 1:
You're going to want to begin with a square piece of paper then fold and unfold each corner to the opposite corner. Then fold each corner into the center of the paper and unfold it. With the smaller triangles on the corners fold the tips into the base of the triangle and refold the whole triangle back to the center.
 Step 2:
You're going to want to turn the paper around and again fold the corners into the center of the square so there's a cross in the middle. Finally fold the tips of the square again but point the tips upward and you'll be done with the first module. You're going to need to create a total of 18 of these modules in order to create the Rhombicuboctahedron.
 Step 3:
Once you have all the modules you're going to want to connect them by folding down the tip of a point and insert it into a the pocket of another point and repeat until you're able to link eight of them in a circle.

 Step 4:
Link three more modules and attach it to the top of the circle by inserting a point on one end and insert a point on the opposite side of the circle
 Step 5:
Add two more modules to the remaining points of the top middle piece creating a kind of dome
 Step 6:
Recreate the dome on the bottom and you'll have  a Rhombicuboctahedron.
Notes:
So overall the entire process of creating this thing took over an hour for me as creating over 18 piece as some had to be scraped because they didn't fit or didn't turn out as i wanted. Arranging the Rhombicuboctahedron also took some time as some points wouldn't fit or stay in place so I kind of cheated and stapled some points together to keep the module together. Folding the pieces was pretty easy but arranging the pieces was definitely the hardest task and the book even says " The difficulty of assembly may be intermediate even though the difficulty of folding the individual modules is simple" (Gurkewitz and Arnstein 10).

Question:
So i definitely scrapped some pieces due to them being less then ideal but i also kept many which were close to being good but weren't. My question is, when folding origami or creating anything, do you guys keep going when you make a small mistake or do you redo it and do it perfectly?

  1. This is a really cool topic! I like how it focuses more on geometric shapes rather than traditional designs. I think your "Rhombicuboctahedron" turned out really cool. To answer your questions, it really depends on what I'm doing. Usually, I do have a tendency to keep redoing it rather than continuing even after messing up.

    1. First, thanks for commenting and one of the main reasons i picked up my IRP book was because of the interesting designs. I've always been trying make everything perfectly but i'm gradually getting out of that habit
