Haha... kinda recycling some excess acrylic sheets lying around. They were heading to the dump, and I picked them up, gave a good wash before reusing them. I use an acrylic sheet cutter, similar to the photo below. Its used like a penknife, slicing a few times before breaking it over the edge of the table. However, you might need to file the edges flat. I use a Dremel tool for this.
