Cardboard Foot

I use these to hold pieces of cardboard in place around the bed while printing that helps cut down on air drafts hitting the print. If your cardboard is to thin, just place painters tape along the bottom so the foot will hold better. I use 12" x 12" pieces of cardboard and use 2 of these per piece. You can cut your cardboard to fit your setup. Make sure that the side pieces butt up against your front and back piece or it will draw air through the corners. I usually just throw a couple of paper towels over the top and it keeps it nice an cozy around the print.
