The file 'Banana Tracker V1 3D Printer Model' is (zip,stl,stp,step) file type, size is 9.4MB.
Frame for an antenna tracker built around 0.75" square dowel and a lazy-susan bearing from Home Depot. Free-rotating end uses a press-fit skate bearing. Servos are mounted using exterior mounting tape. Plywood base is 1/2" thick sheets.
The length of the pitch bracket is so that the CG of a mounted Ubiquity Nanostation is balanced along the axis of the pitch servo.

But may fit output shafts from other servos. Shafts are press-fit into 3D-printed brackets and gears.
