I needed this adapter to rise my Xiaomi Cam about 50 mm in my desktop for use with my A1 printer.
Disclaimer:
This adapter is very different from other webcams.
Kerui Desktop Base IS NOT COMPATIBLE with this model.
The model is in two piece for easy print. The base is 1,3 mm narrow than the Adapter, so, is PRESS-FIT with no glue and tools.
