Inserts to help gloves or mittens dry faster after a day on use. Also useful for drying reuseable bags or ziplock bags. Comes in 3 sizes, use the table to pick the size that works for you. Can be printed in most filaments. The photo is an example of the small one.

Note: The Large is too big for BambuLab printer as it requires a 290 vertical height, but I added the file for those who have other printers and can make it happen.
