Bending Plexiglass: In my own case I did use my oven and ended up with 250 degrees F - 15 to 20 minutes and just kept watching till it seemed to sag. I had placed on sheet of alum. foil and removed wearing heavy cooking gloves, and bent over my form for 2 sided front on gift box display. My bend was a soft curve, which was what I was after. As plan on having the 2 box sides -glued together to box top, protect it when I want to store.
