anti wasp lid for guinness 500ml glas - TPU

The lid is for protecting the Guinness from flies and wasps. 
The inner diameter is ca. 0,1-0,2mm less than the edge of the glass, so it fits very smooth, the click is hardly noticeable. I wanted this so "light",  to protect the thin glass from breaking/damage by using.

If you wat this a little bit tighter, you can downscale (in the slicer) the both horizontal axes to 97-99%, just try... The vertical axis is ok.

Printed with TPU, slow speed, no brim, no support.
