Modular Arm for Xiaomi Outdoor Camera

EDIT: Printed and assembled, althought i used way too long bolts it works like a charm, photo uploaded

These parts i made for my Xiaomi outdoor camera, i was getting a bad angle attached to the wall so i decided to make this arm to extend the reach of the camera.

My dimensions:

The black pipe i have setup has 5cm diameter
the metalic pipe i got is 50cm long and has 2cm diameter

The holes are 0.9cm in diameter to fit some bolts i had lying around the house to sucure the parts.

My current setup only has 1 camera facing 1 way, but the modular design allows to add two facing different directions.
