TE Cover Dimensions


I was wondering if anyone would have the dimensions or work files of the extended cover for the TE. I want to make an all black acrylic cover and since Art doesn’t offer that yet, I have taken things into my own hands. I have access to the laser cutter at my university and was going to cut it myself. However, I don’t have a template. I saw the art templates that Art offers however I’m not sure how accurate those are in terms of laser cutting (since they are just cover art templates). Any help would be appreciated. Thanks
