This is cheap enough that you can discard it after if necessary. While test charts can be useful for inspecting the unique characteristics of different lens and camera combinations, other targets like a lens distortion chart (or lens distortion checker grid) are a necessity for the visual effects pipeline to precisely map the unique distortion of each lens used during the production. Typical correction methods use a distortion model defined on distorted coordinates. If you cannot print it locally bring it in a hard board tube.
