Gardena to 13mm / 15mm / 16mm hose connector screwable

I modified the original Gardena hose connector by adding a thread that connects to a 25mm hose (https://www.thingiverse.com/thing:1454332), then reduced its size to fit snugly onto a 13mm hose. Update: June 19, 2020: As requested, I created versions for 15mm and 16mm hoses as well. However, I haven't tested these yet, so you might need to adjust the nut's size accordingly. I also added two different types of nuts - one with thinner walls. The smaller version is perfect for use with this thread, allowing you to easily attach a Gardena hose connector to any flat surface like wood or plastic (as seen on my camping car). Simply fasten it from behind using the provided nut. Initially, I printed the thread with PETG but found that it was too brittle and broke when I added a hose clamp. The PETG version wasn't watertight either. But PLA worked flawlessly! To ensure complete water tightness, I applied an epoxy coating (I used XTC-3D, but other options should work too) inside the thread. While this might not be strictly necessary, it's definitely a good idea to do so for added peace of mind.
