How much of your steering column is taken apart? I recall seeing a piece like that in the guts between the steering wheel and the column, part of the flasher system. But I'm just grasping at straws. Maybe some pics of different views? kinda looks like there are some loops and holes but I can't tell for sure.
If I had to guess, there are 3 different bushings to support the shift tube, inside the column. They are made from, what looks like, the same material as your picture. If so, its probably a piece of one of those bushings.
