This is a replacement for a round 1 cup Pyrex container.

The plastic lids are wearing out crack after years of usage.

You will need to print this from TPU -regular PLA is not flexible enough to make it work...

It slips on nicely and seems to be even watertight.

In case i make one of the larger sizes I will upload the files.

> one update: i also did the medium size lid & printed it for testing - it works well so far!
