These are some unusually shaped shelf pins for a house that I purchased in 2012. The kitchen model that required these was completed in the late 1990's. I have a blog post at http://use-cases.org/2013/07/10/3d-printing-shelf-pegs/ detailing why I crated these.
Note that the price here is the Shapeways manufacturing cost only. Have fun!
