I wanted a good looking but cheap microphone arm for my Razer Seiren Mini. The stand supplied with the Razer is very short and I needed to bring the microphone closer to me.
On our last visit to Ikea I had an idea and bought the Navlinge desk lamp for £12. This lamp has a flexible arm attached to a weighty base, and the arm has a female thread to screw in the led lamp. Just using the arm I needed a male thread to male thread adapter to convert the Razer's 5/8" female thread to the lamp's female thread.
I printed it without support and just had to fettle it a little bit underneath where there is an overhang for the adapter to fit over a screw in the microphone.
Here's the model, hope it is useful to others.
