I wanted to attach a Wyze Pan v3 to the beam in my kitchen so I could watch my bird feeder on the window. 

I built this with machining tolerances in mind and had some issues with getting the screw to run smoothly so I would recommend printing the screw at around 95%. 

I printed every part at 20% infill and 2 perimeters.

The screw should be printed horizontally if you want it to not break.

I’ve included the Solidworks file to adjust to fit your beam, I recommend making the clearance for the beam about .5 inches.
