Spigen back plate for iphone 5 slim armour

following a horrific crash in my quadcopter and the joys of my previous case (http://www.thingiverse.com/thing:542093) i give to the world....... this thing!!!

featuring a pattern that is both triangular AND covers/fits the whole back of the case unlike the last one.

magnificent, just look at it!

(also, as i have recently discovered, this only seems to fit a knock-off Spigen case [got mine off ebay] and not the genuine article my dad has, it's about 4mm too long)
