I couldn't find any adequate options to extend the stand of my Razer Seiren Mini microphone, so I made one! Yoohoo! 

This stand is modular and has three different lengths and print profiles:

1) 40 mm

2) 30 mm

3) 10 mm***

Each extension has two threads: 5/8"-27.

All these extensions are good for stacking and screw into the mic and stand with the default extension.

IMPORTANT TO KNOW

1) Each extension should be printed one at a time or one per table.

2) Print them only in a standing position!

3) These threads are very fine, so the print files are set to extra fine print. If you modify them, keep this in mind.

4) I used a P1S Printer, and with the following settings, threads could get stuck or may not enter when stacking, but no worries! 

    - If it doesn't enter, make sure that extensions are well-aligned and try to push them together when screwing.

    - If it gets stuck, unscrew it and screw it back, repeating this 3-4 times. These problems occur only during the first 5 screwing cycles; after that, it becomes buttery smooth!

5) You may need to use sandpaper or other tools to remove additional support material.

***The 10 mm part is brittle and harder to align because of its size. I recommend considering the other sizes.
