Wanhao i3 plus print bed 200x200mm glass fixture

thingiverse

Cut your glass to 200x200 mm and secure it with four screws fastened into the corners. The small slits permit adjustment for a precise hold, then tighten the screws. You can retain the original board plate, as my design accommodates the additional width. The glass is held in place on its sides only, allowing easy removal for cleaning (a mark tracing the word "WANHAO" was applied to the back of the glass to ensure correct placement).
