This S-shaped chain link printed very small makes a fantastic chain for anything ornamental or even 3D-printed jewelry. It is a very simple and just snaps together. Print tons of the S-links of any given size and then choose and print the end parts of your choice to create a useable chain. Super fast, simple and effective.

The smallest version of the chain makes a pretty decent light necklace if you want to keep glasses with you for example. And, the thicker chain could be used to keep more substantial objects with you or attached to something. The possibilities are endless and this chain system allows you to create literally any length as each link is snapped together individually.

I have designed it in 3 sizes. I started out just scaling it and that works quite well. But some of the end pieces do not scale so well and also I really like to design in multiples of the nozzle widths which is more difficult when scaling. So these parts are all 0.4mm multiples designed to be printed at 0.2mm layer height.

3 Sizes

These are the three sizes. Each size is a series of components that I have labelled with the S-link length. What I mean is, the 7.2mm Star for example is not 7.2mm in size. It is designed to work with the 7.2mm S-link.

7.2mm S-Link 1.6×1.2 9.6mm S-Link 2.2×1.6 12mm S-Link 2.8×2.0

Printing:

You want to print a ton of the S-links and then snap them together. All the other components are just end pieces which you can choose from. The S-links print fast and very easily.

If you are not sure which size to print, try the middle size first – it makes a very nice chain weight. And, to calculate how long the chain will be multiply the chain size by the number of links. For example, 100 pieces of the 9.2mm S-links will create a 100×9.2mm = 920mm chain.
