Summary

After printing these links out at 40mm in length, I found that they fell apart very easily as the gap used to link them was far too great when the link was scaled up. As this material has an amount of flex in it, I felt that the gap could be reduced to zero and still allow the links to be fitted together with ease. This also facilitates easier application of glue to keep them together.
I have now included a picture of this design in use and one can clearly see that they do in fact join together.
