Agreed that the bowl is not the only point of failure. The stick nub is made of a much harder plastic than the bowl. In this design all I had to do to the nub was lightly file it to a uniform shape. I have not come across any that were worn down to nothing. The replacement part has room for adjustment where you can fine tune the height to accommodate different lengths of stick nubs. The gear cradle is a problem and a difficult part to pull off in 3D printed material. There is already a Shapeways user that has modeled the X Y axis cradle, however I don't think the material is strong enough to resist bending under the spring pressure. I have come across a seller on eBay selling new 3rd party replacement that seems promising. I don't have any plans to model them at this time. While this is not a perfect solution, It does bring useless completely floppy sticks back to life. The stick snaps back to center were before it was always limp to one side. The worn down bowls are the death nail for these sticks.
