Holds my Deity D4 Mini with no problems, although I'm not sure how well it will holder bigger mics. The mic does wobble a little bit since the original mount has little shock absorbing nubs but I haven't found it to be that big of an issue.
Print Settings:
Printed with default settings in PLA with 0.2mm layer height
To use the least amount of supports, rotate the model 138 degrees in the y axis

I used the Creality Print Slicer, printed without a brim or any bed adhesion
The author remixed this model.
This model uses the coldshoe from the original model but I created the rest of the adapter
