Aviom A16ii replacement buttons

Aviom A16ii Personal monitor Mixers lose their buttons for fun! These button caps replace the originals. They clip in to place slightly more firmly than the originals, and are easy to print and replace if you do happen to lose one.
The illuminated ones have a 3mm hole through them, through which you can pass and glue in a 3mm acrylic rod or fibre optic, available cheaply from many suppliers including ebay.
