I'll have to install a Dock II board and give that a try. I think I have one, I always thought my Dock+ was a Dock II.

The gears are nylon, so they've some slop, shock absorption built in. I'm not sure about nylon prototyping? I think I've got a spare (extra) motor/gear assembly.

You can also just remove the assembly and plug the Duo in manually for lidless config playtime.
