Description
This saves your ears when wearing your FFP2 masks for longer than just a minute :-)
Print it using PET (around 30minutes): no post-processing as PET is flexible enough to bend over your head.
Small enough for a print on a Mini!
You want to sell this?
Please ask in advance and consider a small donation to me or a charity organisation.
