This is a remix of my large paperclip (1" x4"). My goal for the paperclip was to make a paperweight and I think this does it. At 50% infill its heavy enough to hold papers and big enough to hold them down (paperweight next to Letter size paper image included). One issue I had was that it is very prone to coming off the bed due to thin contact with the bed so I included a brim to resolve the issue (you can try if you want. Otherwise very happy with outcome - a 3" x 9" per mat (12mm diameter)
