Gen 4 cup holders that won't hold cups!

[birdseye]

 

 

The cup holders are misnamed as of course they are more like bottle holders,  we often used to take a flask of tea in our old gen 2 and the cups fitted in the holders, however with the new gen 4 the cups fit in but the spring loaded grippers push them straight out.!

I spotted a thread where someone had fitted inserts that allowed normal cups to sit inside but can't seem to find it.  Has anyone found a solution or does everyone only use them for bottles?

Would a sawn-off Fairy liquid (or similar) bottle to the trick?
