Steampunk Antique Stethoscope

I created this antique stethoscope for my husband's plague doctor steampunk costume. This piece fits on the end of a standard stethoscope (I found a cheap costume one from Goodwill). The holes are 8.1 mm diameter. I also created a single hole version (that I was originally going to utilize) before deciding to go with two holes in case you prefer that option.
