I modified this to fit two smaller lights on - similar to these: http://www.ebay.co.uk/itm/141204897885 (though I was actually sent two half size ones - hey ho). Also curved the edges for aesthetics. You need to build this with the mounting face on the print bed - no other way will work without it coming lose (especially if printing in ABS, and even then I recommend ABS slurry to stick it down real good).

Probably doesn't need to be in ABS, but anything around the print head should be reasonably heat proof.
