Baby Mobile Stand for 24mm or 25mm wooden bars

I created this stand to use baby mobile on baby carriage, or wherever there is no possibility hook it.
I used two 150 cm long broom handles with 2.4 cm diameter, 3 flat head screws and a conical head wood screw.
It is completely modular, by acting on 2 screws, you can change the height and length of the arm.
For added security, the ends can be glued, I at the time did not consider it necessary.

Rotating the objects, no need insert supports.

Edit: I have also added files for the 25mm diameter bars.
