Penny pendant necklace
Okay I'm a super beginner (and I'm old) when it comes to designing things. This little pendant is designed to hold a penny. I like Indian Head pennies so that's what I used.
If you try this, you might freak out a little. On my ROBO with .3 layers, I pause before layer 11 starts. Drop the coin in the hole that is just it's size, then hit resume. The freak out comes when the print head goes onto the coin and starts spinning the coin for the perimeter that will print on the coin.
After that it seems to work pretty well. The pendant is designed so the coin will spin. If you want it heads out, the head can be up. If you want it "one cent" out, spin it so that's right side up.
Oh, and it's amazing what one can come up with and try after a few adult beverages :)
