3d printing bed build surface for 2 bucks - polycarbonate (Lexan)

The polycarbonate (Lexan) sheet is great 3d printing build surface. It costs less than 2 EUR (well, it appears online is more expensive - best is to find a local company that cuts PC sheets. I bought 1m2 (9 plates) for 18EUR) and assures warping free printing for almost all filaments - ABS, PLA, Wood, PETG, Flex, etc. Update: If you print PC filament it also sticks well on a PC sheet - Can you bend the PC sheet in order to detach the part easier?
