Based on my "like"able cufflinks....my office colleague suggested making it symmetrical, so that it doesn't matter if it twists and turns on the tree. It's made from clear PLA, painted with blue acrylic paint. Apart from the raised outline, the hand itself is unpainted. I used medium resolution and supports, no raft. I noticed that the hook attachment is a bit wonky, but works well enough.
