This Multifix holder is designed for Type A!!! (Maybe you can scale it up or down for another Type)
On the bottom of the holder there is a 4mm wide bar, which runs as an anti-rotation in an aluminum rail (T-slot). If this is not needed, it can be milled off quickly or the CAD file needs to be changed.
For mounting an M4 + nut is required.
