Hi All,

I'm designing a part where there is a cylindrical piece sliding into a slot with a spring loaded backing.  There are also ball plungers that move while the cylindrical piece is sliding in and out.

I want to be able to drag and move the cylindrical piece through the slot, but at the same time, I want the balls in the spring plungers to move when engaged, and I also want the spring loaded backing to move when engaged.

I'm able to easily mate the two separately.  For example, I can make the balls tangent to the cylindrical piece and they will move appropriately (although I cannot drag the piece away from the balls).  Similarly, I can make the cylindrical piece tangent to the backing.

I ultimately want to move the cylindrical piece anywhere within that slot and only have the tangent matings enable when it actually hits the balls or the spring loaded backing.

Any ideas on how to mate this?  I've attached an image of the assembly.
