So, my solution was to make my own. I would not recommend this with any pen you have sentimental value for... or that can't be replaced for less then 10$. If you read the title and thought Jinhao had come out with a desk pen... I am sorry to disappoint.
We start with a piece of beveled wood. I decided I like it a little square, but round works well. If you don't have a router, it is easy to find pieces this size at hobby and craft stores. It was important to me to have a little heft... but probably not necessary. Part of the reason I went with the Jinhao 159 is the amount of metal in the pen. I don't think it is going to put undue stress on the pen or cap.
I removed the cap finial and the clip The finial is brass. I don't think this would have worked well if it was not metal. I carefully drilled a small hole and inserted a screw.
I drilled a larger hole in the wood, so that I could angle the pen down when it was drilled in.
I dry fitted everything to make sure it was going to work.
I stained it with some cherry wood stain... I liked it but realized I wanted more shine.
I am very happy with it. It is sturdy, it is easy to remove the pen and I am happy.
I really like the actual pen a lot. I have heard people complain about the lacquer chipping off, etc. I like to think this will help avoid that.
