I'm getting flashbacks (melted rough spots) on the back of my cut acrylic pieces thanks to how strong the P2 is. I made some acrylic sheet risers to lift the material off of the slats/prisms to prevent flashback marks on the back of the acrylic sheets. These risers also have a bonus feature - it helps you see the edges of clear or dark acrylic during camera placement.
Open the project file in XCS and laser cut the pieces out.
Starting with the corner pieces, glue the 3 wide pieces on top of each other, and then glue the thinner piece on top afterwards, making sure all pieces are glued flush. This will create 4 layers. Repeat for all the remaining corner pieces and the straight side pieces.
I used clamps to help hold everything as it dries.
After everything dries, it is ready to be used. I placed the risers on my slats, and the acrylic sheet on top. The side riser pieces are not really necessary for a new 12 x 12 sheet, but can be useful for larger acrylic sheets or used scrap sheets.
I hope these risers help prevent flashbacks for you.
