This model is a mount for the BambuLab A1 to attach a Raspberry Pi Camera module to it.
This is only the mount.
It is supposed to work with the Front and Back part from this model: https://www.thingiverse.com/thing:3294512
(For the camera module v3 you can use the back part from the link before with this front part: https://www.thingiverse.com/thing:5926129)
There is a need for one M3 screw with a length of 16 mm to attach the camera case to the mount.
