Prism Pencils (pack of 85)

Prism Pencils (pack of 85)

£46.37


Build your own rod packing structure! The set contains 45 square cross section pencils and 40 hexagon cross section pencils, which can either be built individually or combined together into a superior 7-directional rod packing configuration.

Follow along using the Matt_Parker_2 video or with Daniel Piker's manipulatable 3D model. Here's a paper explaining the mathematics of rod packing along cubic axes. When you've built your 7-directional model, here's what a sweep through the cross section would look like.


Sorry the set is quite expensive. This is just the cost price I originally paid to get them made. Elastic bands are not included.

SQUARE: 15 Red, 15 Green, 15 Blue
HEXAGON: 10 Yellow, 10 Cyan, 10 Magenta, 10 black
