Biqu B1 SE Plus mount for the fantastic Articulating Raspberry Pi Camera Mount
It can be printed without supports and I would recommend a 0.2mm layer height with 20% infill.
This is an “upside down” model with the connectors for the links of the mount system intended to be on the bottom of the printer once attached (this is to allow enough room for the bed to move fully forward)
The author remixed this model.
