The list of problems with my old servo attachment was long, so I revised as best I could. One of the biggest problems was that my prints are weak and keep coming out "spongy" or full of gaps, and this may be due to a clogged extruder. On the flip side, this problem forces me to strengthen my design instead of just adding more plastic. My solution was to add a second rod slot behind the fulcrum, so the twisting stress gets divided between the ends, and that should effectively double the durability. Another problem was slipping on the servo, so I decided to mount this on a servo horn, not directly on the servo sprocket.
As expected, I turned out a couple of weak models, but they fit correctly. I drilled out my rod sleeves this time so the skewer wouldn't split the seams. I ruined my third servo horn when I forced a large drill bit through. The design needs a few more improvements, and my printer needs some service.
