One more type of head to the my studio setup (it could be used for the horizontal also) - Nikon BHMJ adaptation to the 8020 type extrusion, using 3D printed sliding adapter
This time I used velcro instead coupler or magnets, it saved me space and it is more forgettable in the case of misalignment.
Instead BHMJ it could be used for the Arca-Swiss type plates, 1/4 standard screws or (using cheese type holes & 1/4 nuts) - other custom stuff.
