1060: Second Stellation of a Cuboctrahedron

To celebrate the release of his lovely new book of modular polyhedra (must get me one), Fergus Currie offered an early morning (for me at least on the opposite side of the planet) workshop on how to fold his second stellation of a cuboctahedron:

I set an alarm, awoke at 1am and folded along with Fergus.

I like this modular a LOT – each vertex is a single piece of paper – it works well with paper that has only one side printed or printer paper. The design is ingenius, the angles odd and exacting but you get into a groove and they make sense in the end.

I went into production line, and using the template to establish the initial odd division, I found that using a fine ball stylus and ruler it was easier to lay in the intermediate creases with the accuracy to make the vertices crisp and accurate.

Once I had 24 units, I then interlocked them in groups of 3 using the narrow tabs and pockets – these interlock really tightly and I could not imagine trying to do these later. I then joined the triples as they tile on longer tab-pocket sets that slide together with a little encouragement. Eventually the units combine to become this wonderful spikey ball with unique geometry.

I have folded this over a couple of days, taking time to savour the process, and am really happy with the result. Fergus’s modular work has a unique flavour – his approach, often, is to make the whole spike with a single sheet – many other designers use a module per facet or side (meaning many more modules and a LOT of issues joining accurately).

I must buy Fergus’ book (available here: https://www.tarquingroup.com/books/paper-models/compound-polyhedra-modular-origami.html ), there are lots of spikey complex lovelies inside, some I test-folded a while back. Thanks for the chance to fold along with a legend Fergus!

  1. Thank you for this amazing review and making a superb version of my design! The online live session was great fun despite the crashing computer and the power cuts!
    I am so glad that the attendees liked it and came away with something. I was a bit flustered at the beginning where I was explaining some of the history and math because the power came back on four minutes before the start and the internet connection was reestablished literally two seconds before going live. I had a lot of other stuff lined up about the history and wanted to tell some more Star Trek and origami jokes. Next time maybe.
    My plan is to do about one of these online tutorials a month for models that will not end up in my books because the series they belong to is short.
    My current book project, as you might already know, is a collection of stellations of the Rhombic Triacontahedron. I have a tentative agreement with Tarquin for this one but, as yet, no fixed publication date, but I guess next Autumn is good estimate.

    Thank you once again Peter, for all your support and advice.
    Merry Christmas!
