Summary

This is a helm which not only looks cool, but helps you to keep the insects out of the opened beer bottle...
....no fun to drink a living wasp!

I love the original design, but since I run the models on an FDM printer, I rearranged the orientation to fit FDM supported printing and also healed the stl files.
Also I did a now conic pin incl. an end piece in two different widths. you can choose which fits best your printer tolerances. Also the little edge plate makes it easier to print.

Thanks to rob_nexus for this awesome design!
