I just picked up an Enterprise playset. It's pretty much as I remember it, except for these little plastic rivets. Out of the box, one on the transporter had popped apart, but was easily reinstalled. But another on the right side of the central bridge floor is missing the pin.

Does anyone know where I might be able to get a replacement? Whether someone selling the original part, someone selling a shapeways 3d print, or a substitute part?
