This simple clip-on helper for cloth masks of 19 cm width helps to close the gap around the sides of the nose. It may/may not fit your face; I shaped it to my face to improve the fit of cloth masks sold at our local supermarket. It keeps my glasses from fogging up and stops the annoying draft into the eyes while exhaling.
Not meant for prolonged use since the plastic at the sides is in contact with the skin; then again the cloth masks are also a stop-gap measure.
UPDATE: I added the FreeCad file so you can edit the shape to better match your face. The element to look for is "NosePath" inside the first AdditivePipe.
