Repair the cap on your taps

The cap covering the screw broke on the hot tape before the plumber has left the flat and the second broke 2 days later. I live in rented accommodation so decided to go ahead and repair them myself. I've deliberately left air space underneath the cap so if they need to be removed I won't have to spend hours gouging it all out. They've lasted over 3 years so far - my first every Sugru project!
