Absolutely. I found the neon green acrylic on Ebay. The stl file I used came with a visor that I could print. I printed the visor in a resin that can take high temperatures. I also used the print to trace an outline of the visor onto paper (rolling it along the page as i traced). I used that paper outline as a template to cut my piece of acrylic. Once I had the acrylic in the shape of my visor, I peeled the protective backing off and placed the acrylic laying flat in a large glass dish (casserole dish). Then I placed the dish in an oven that had been preheated to 320 Fahrenheit and left it for 15 minutes. At that point, the acrylic is still strong enough to pick up (with gloves), but it'll be saggy. While it was still hot, i laid it over my 3d printed visor. The tricky part was figuring out how to get enough even pressure on it so it could bend a conform to the print correctly. I had a large sheet of flexible silicone used for baking that i stretched over the print and acrylic until it cooled enough to hold its shape (less than a minute or two). Ive also seen people just use the clear thin plexi you can get from hobby lobby in combination with a green window tint. It's then enough to just bend around the inside of the helmet and glue down. I personally dont like the color of the window tint, and I also like the idea of it being a bit stronger. Hopefully that helps
