Party/Minikeg plug

A plug for party or minikegs to keep dust and bugs out, when the kegs are not in usage.

Two of my kegs got a plug, so that I can close them after cleaning and nothing can get inside.

I couldn't find the plugs online, so I designed them in FreeCAD.

I used TPU, because the originals where also a little bit soft. But the prototypes where printed in ASA and they work as well. Even PLA oder PETG should work just fine.
