This is great, I made one and it works well (in the process of making one for my whole team). I have one question on this design, and I think I know the answer, but why is there a flimsy little washer that holds the center bearing in. That is the part im most afraid of snapping. My guess is you did this to not have to worry about supports if you made the center solid and thicker. My first print go-round, the middle of the hole of the base with the center bearing didnt come out as nice as was needed for a great hold and I also was concerned about breaking. This thing dropped out of my hand from about 4 feet up and hit the floor and came apart (luckily it was the washer) but I want to be able to throw this thing in my bowling bag and not worry about it falling apart. Even with supports I think a solid center area (or maybe even a thicker locking part) might be a good upgrade.
