Some sheets of 2mm Alu would be nice, guillotined down, but that looks a
bit pricy unless I happen across some. Thin MDF would be too weak, I
think. FR4 PCB material might work, but the offcuts I see at work are
only 10mmdeep or so, and some treatment would need to be applied to the
edges - GF splinters are not nice!

I use that stuff for lots of things - and never had a problem with GF
splinters. I would normally give the edges a rub over with a file, though.
