This is a simple one but I figured a few people out there may have a use for it. We have a rolling pin with removable rings to change how thick the dough rolls. It comes with several, but the wife wanted a 12mm or 1/2 inch dough roller so I made one. You can adapt this to any size rolling pin and any thickness you want. I printed mine at a fairly high 35% infill as it will be under a bit of pressure.
