UV LED Exposure Box

Step 22 Glass and Foam

Cut some thick foam rubber (about 1 inch thick) to the same profile as the shelf. Make the cuts in the foam by compressing it with two rulers side by side and then run a craft knife between them. Then Place the foam on top of the shelf and the lower glass on top of the foam and then run a fabric strap around the ends of the glass, adjust the length of the straps so the glass sits flush with the top of the box and fix the straps to the shelf.
