For reasons unknown to me, the manufacturer of my breakfast curd recently changed the lid on the packaging. The old lid was handy, you could easily close the cup again so that the curd did not dry. With the new aluminum lid it is not so easy, also because this tears easily when opening. So I designed a new lid and printed it out!

The two parts can be printed together and then simply put together with a little force. In my printout, the whole thing holds together without glue.

Note: In 3D printing, bacteria can easily accumulate due to the surface structure. This lid does not come directly in contact with the curd, but should always be cleaned well with dishwashing soap before reuse.
