Uncle Dan (click on the banner below) has assembled the notes on a project that was initiated in the Google Geodesic Help Group. Below you can follow how participants came to offer instructions on how to build a spherical dodecahedron model made of paper.
You can download a Word document version of this page along with larger versions of the graphics by clicking here.
Below is a link to the Sketchup file for this model:
Taff: Papercraft sphere of buckyball/soccerball symmetry • This model can be constructed of paper, folded along curved lines • Paper cut-out patterns provided in model • The single pattern, of which 60 are required, scaled to fill a sheet of paper, will produce a large model • The pentagonal pattern, of which 12 are required, will produce a smaller model • Construction details, depicting how the 3D SketchUp model was produced, are included • Buckyball sphere was produced first, then the resultant module was “unfolded” in SketchUp, to create the paper pattern • (Tabs not yet added • I’ll get right on that)
Dan: Taff,– Please post pattern for “Buckyball Sphere – Curved Folds”.
Taff: So, you discovered that posting, eh, Dan? I’m currently doing a paper test-construction, to double-check my work. I’m using a pent-ring pattern, to ensure that the papercraft won’t be too big. You can peer-check the pattern, if you like….
Taff: Considered it, but few people know the reference. More folks know “buckyball,” particularly the younger generations. That’s the audience, to which I’m directing most of my efforts. I figure, if you’re our age, it’s too late, already — you’re beyond reach (although, Dan appears to be an exception to the rule.)
Dan: Taff, — I have begun — two pictures attached. I have put in double flaps, one above and one below at each joint – I don’t mind at all that they show.
Taff: Card-stock looks to be working better than plain printer paper (my effort).
Dan: Taff, — Yes card stock works very well with these curved folds, model retains strength very well. However, my printer doesn’t like it very much; I have to help the paper feed though manually doing only one sheet at a time; sometimes I get blotches of ink.
Dan: I managed getting it half done before retiring for the night.
Taff: Wow, the large circles “firmed up” nicely. I was concerned that the folds might be too shallow to provide rigidity. Looks like it’s going to turn out all right, after all….
Dan: Model Completed – That was fun.
Taff: Nice! I’m relieved that the model pattern works (in reality). I definitely have to visit my hobby store for plastic stock, to make my own….
