Corkscrew

My brothers girlfriend wanted a corkscrew as a keychain, therefore I designed this. My plan was to put a magnet on the stick and the corkscrew to keep them together (the stick is supposed to fit inside. Then when you want to use it you can put the stick through the upper part and pull. The second hole is to put anything though for attaching it to a keychain. As for the printing, it did not go perfect yet with my printer so i had to glue some stuff together later. I am also not sure yet how strong this design is, but I printed everything on 100%.
