This is a remix project of a Raspberry Pi camera Arm. Instead of requiring bolts to attach the three pieces, each piece is connected via a ball joint, requiring no additional hardware.

This design allows the the arm to swivel and tilt with great degree.

The four grooves surrounding the receiving end of the joint allow the arm to tilt further past the top edge, by aligning the corner of the arm into the middle of the space (see the first picture).

This design can be edited using Tinkercad - https://tinkercad.com/things/9WGoSMfpmMw.
