Gloomhaven Player Dashboard (/w bed adhesion tabs)

I love the Gloomhaven Character Dashboard by richifever, but my printer struggled with it. Given the size, and square corners, it tended to warp somewhat. I had a print come off the bed and mess up my hotend. After further messing with my settings, print orientations, etc. it became clear I ALSO needed tabs around the corners to keep it stuck.
