Finger Circle Key Chain

thingiverse

Just whipped this up for some laughs. Add it to your keys and give whoever looks at them a good whack! Had to include two STL files because the thumbnail wasn't showing the front view initially, so make sure to print it face-up! This design stands 3mm tall, with a 0.5mm inset allowing you to swap out the outline for a different color if you want to get creative. Have fun!
