So decided on another final print Jimmy had the idea and gave me help in finding how to creat thread for the 3D print. It was found or so I believed that the thread were a 20/410. So following an intensive way in which to create the threads the were done. Only problem was they weren’t fully attached so I was able to connect them to the cylinder. I then had to put it on the bottle design which went ok. Another problem was the software didn’t like the thread and kept crashing when trying to connect things together plus both files are to big so the had to be done on a desktop or laptop.
