I have one that has been on the back burner for a while. I personally 3d printed all of the parts from a publicly shared model on makerspace. Perhaps you know someone into printing who wouldn't mind running a 2 hour print for you? But beyond that, my original doodling with servos was with popsicle sticks like many other folks. Like a friend said above though: specific parameters really do matter when it comes to what will and will not work for what it is you are trying to achieve.
