Tap Spout/Flow Straightener

Our kitchen tap spout (whatever it's called) failed and unless it's replaced it sprays water everywhere.

Until the new one I ordered turns up this printed replacement seems to work. I used the 2mm o-ring that came with the original to seal the part to the end of the tap.

I have no idea what model the tap is, I got it at IKEA and it may be an M24 fitting - we'll find out when the new part comes...

Photos show the working version (fitted) with the previous version that was a bit too small
