I bought a 4x8 sheet of foam insulation the other day to practice on. Since my work area is 24x24, I just cut the whole thing up into smaller pieces. As cold as it’s been the last few days, I noticed we have a severe draft in my laundry room. No problem! I have foam I can put in there! Uhh… the window is 32 inches wide… my phone isn’t big enough any longer. Fear not! For many years ago I made some flash jigsaw puzzles, and have a small script that generates SVG puzzle pieces for me. I tweaked it a bit, made it generate one long squiggly line. I converted it to DXF with Inkscape, and then generated two gcode files in Estlcam. One for a right side cut, and one for the left side cut. Now I have a big enough piece of foam to put in the window for now.
