I will have a play with the off-cut. Not sure how well it will work with this one though - the plastic is a light colour, with a general grey paint over it all, but then a thick layer of soft black on the front surface. Not sure what it is, but it feels like the old Thinkpads used to (y'know, before they became Lenovo) so I have a feeling that may melt back quite quickly.

Will let you know how the experiment goes.

Cheers guys
