Steam Lid hole cover replacement

A small replacement steam “flapper” for an old plastic lid for a favorite bowl.   I know its likely not food safe but I mostly wanted it for blocking steam “after” I heated up the glass bowl it covers.  

I made a slight lip for the shorter and narrower post so it would just stay in place after a little extra effort to pop it into the opening.  It was a first guess but it worked well.

PLA was used to test the fit, then I printed it in Blue TPU.
