108: David Brill’s Bolt

When I first saw this model I thought it was not possible, but thought I would give it a whirl anyway:

This is a bolt, box pleated to have a functional thread and a beautiful hexagonal do-uppy endy thing (sorry, no idea what you call the end you use a spanner on).

It was a fascinating exercise in crimping and pleating that did not come easily – the pattern of valleys and mountains was challenging to fold in pre-crease stage and more torturous to collapse. I found it difficult to reach inside the tube during the early collapse stage (fingers were not long enough to reach) and resorted to using the bone folder to help out the first few crimps.

This was folded from the appropriately named “Brilliant Origami” by David Brill. It has an accompanying model (the “nut”) that I shall try for tomorrow – they form a pair – could be interesting.

  1. why not put a photo of the 15 step 14 where you can see on which layer of paper do the mountain folds and valley to get the thread ?
