Medium chain - alternating coloured links

A medium sized chain with links of alternating different colours.

Each link is 20mm x 13 mm, based on a Ø4 wire size.
You end up with 100 links if you use them all. This is an extremely compact way of making a continuous chain with alternating links. You can make any length of chain by linking in chains as you build.

So the way this works is:
•do one complete print in one colour. This will give you 50 'yellow' links that you remove from the build plate.
•change colours (eg blue) and start the build again.
•When the build is about 15mm high you will be able to drop the 'yellow' links on to the partially formed 'blue' links.
•Have fun adding the 'yellow' links without stopping the print. It adds a certain challenge to a fun build.
