(Attention: I do not know my way around well, nor have I been able to check whether it really fits together!)

The best I have found so far in terms of shock mounts/spiders for the NT-USB Mini is a flat shock mount and a normal microphone stand. The whole thing would look like the picture in this Amazon review: https://www.amazon.com/gp...

Unfortunately Digitec does not offer the "AUPHONIX PRO Microphone Shock Mount" or not that I know of.

I have found the following two shock mounts so far:

Thronmax P2 Metal shock Mounting
Blue The Radius III

As far as I can see, the Rode NT-USB Mini has a mount adapter from "3/8 to 5/8 thread adapter" (info from an online shop... I haven't found anything on the manufacturer's website). These should be the most common connections. So other shock mounts should also fit, as long as they are flat.

The last alternative would be a 3D print: https://www.thingiverse.com/thing:4478...

No, unfortunately, no spider is included. The scope of delivery includes a usb-c cable, a stand and a thread for a microphone arm. I hope I could help you
