This is a very basic and perhaps unsophisticated fly swatter. My aim was to make it as simple as possible and not introduce any fitting problems. So there is no pushing one part into another, etc. The protruding spigots of the locking washer locate in the swatter and handle at the same time. A very basic nut and bolt fixing holds it all together. You could easily buy a cheap swatter, but this was my first attempt at printing in nylon. As I also needed a fly swatter, I was testing out the flexibility of nylon and it seemed to work fine.
