US CPSC Small Parts Test Tube (Q41823)

This will allow you to test toys for small children for potential choking hazards. It was developed by the US consumer product safety commission as part of their procedure here: http://www.cpsc.gov/businfo/testtoys.pdf I've also included a small section that has dimensions of the part to assure you've printed it correctly. I really wanted to make something my daughter could enjoy right now, but in researching how toys are found to be safe, I came across this part. While it's probably not expensive to produce, it's still cheaper to make at home I'd imagine.
