The part was printed using Proto-Pasta's Aromatic Coffee a HTPLA at 0.1mm layers. Printed laying on the side as shown in the photo, a little support is required under the ring loop and the tapered plug. Cleanup the supports on the bottom of the taper plug for a smooth surface. It should fit the std disposable coffee cup lid but you may need to scale up slightly depending on your material to obtain a snug fit.
