More detail on rod packing in this paper: journals.iucr.org/paper?S010876730001151X
If you want to watch the extended cut, with every excruciating, pencil-pushing moment included, head over to this video on the second channel: youtube.com/watch?v=EsBqeGtThW8
You can also watch the original "How to build a Hexastix in 72 easy steps" if you just want to build a Hexastix. In 72 easy steps. youtube.com/watch?v=DelH1S32dOg
If you need 85 custom pencils in your life (The 67 you need, plus we've put in a few spares) you can buy a set while stocks last over on Maths Gear. Sorry the set is quite expensive. This is just the cost price I originally paid to get them made. Elastic bands are not included.
