Inner glide ring designed to snap inside the grommet interior to ensure a smooth, noiseless draw without scratching drapery pole.

This design was made for what appears to be the most common size curtain grommet on the market. You will probably have to make a couple test prints adjusting scale / settings as needed depending on how well your printer is calibrated.

It is recommended to print in nylon or PETG, with a brim (with a 0.16 mm to 0.2 mm brim distance if using Cura to help with removing the brim easily.), 0.2 mm layer height, and 0.44 mm line width.
