RTV tube plug

This is a plug that screws into an RTV tube to keep it from drying out. I saw something similar and thought I could make a better one. I print it laying on its side so it will be stronger. The file size is unfortunately huge. The conical part is a very high resolution mesh. This is because I used Sculptris to shape the cone and draw the thread on it. Sculptris needs a lot of detail to allow a smooth result.
