I dont know if anyone touched base on this but you can cold bend lexan in a break, for making a turtle deck out of lexan alone, it can not be M-5 or M-10 lexan it has to be standard lexan it can be tinted, best to use a Die break over a box or finger break unless you have one where you can adjust for thickness, add 20% of the thickness on an adjustable finger/box break from the leading edge of fingers to the edge of lower plate edge
On a die break use a .03 radius edged knife or 30• degree die, dont use a 90• degree die, you need to go past 90•degrees during bending procedure, if you have some scrap left over after cuttting blank do a practice bend on scrap
