Bierhelm Freiwillige Feuerwehr
This helmet is to protect your beer or soda from insects falling in. Based on an old helmet the voluntary fire brigades in Germany wore.
Another effects is that you always know what your bottle is.
Ifused two Thingies and created a Beer Bottle Helmet for 0,5 l Euro glass bottles.
I used a 50/50 mix of Anycubic Ultra Tough V. 2 white and ABS-Like white Resin on my Elegoo Mars Pro for this to get the wanted rigidity and flexability.
