WHERE CAN I FIND THE GLASS THAT GOES ON TOP OF HEAT BED FOR REPRAPGURU DIY RepRap Prusa I3 V2 , THEY DO NOT SELL THE GLASS AND ALL THE GLASS I HAVE FOUND DOES NOT HAVE THE CORNERS CUT AND WILL NOT FIT WITHOUT THE CORNERS CUT.
The glass that came with mine was rectangular / narrow to fit between the screws. It didn't have the corners cutoff. If you're in the U.S., just go to Ace Hardware and have them cut you a piece. It'll probably cost you less than $5.
