Birthday earrings 20-29

Birthday earrings for people, ages 20-29. Hopefully I will be making more of these, I'm going to try to get all the way from ages 8 to 100
Do not sell the STL's for this, if you want to sell the printed thing, please comment.
They are perfectly balanced even though the hole is off center because the first digit is bigger than the second. Go to my SF Giant's earrings to see how to make cool infill patterns.
