Cannon from Castle of Buedingen

50 years ago I saw a cannon at the castle of Buedingen in Germany. After I took several photographs I built a model of it made from steel and wood. To make it more decorative I designed the metal fittings a little bit ornate. Some time ago I went to see the cannon again for further details it wasn't there anymore. So I can't say what type and what size it was. After I uploaded the naval cannon https://www.thingiverse.com/thing:338952 I also wanted to design this one, but I didn't know how to make proper printable wheels. The only way I found, is to make them in the same way as in reality. But the spokes where still a problem, until I decided to split them in half. The most realistic way is to make the felloe from 6 segments. If you want to use the complete felloe in one piece you must take the split hub. So you can first put all spokes into the felloe and then push the two half hubs together. If you prefere to print the wheels in one piece you can take the Remix that was upload
