I've always wanted to design a stick... here's my take on Pickett from Fantastic Beasts.
The hands are a difficult print. I was not having much luck with Slic3r's supports so I added them in Meshmixer. You can add your own or use the pre-support file..
You will need to print "Bowtruckle Leaf Flat.stl" twice.
The leaf prints flat and should be bent using a heat source. Slowly warm up the plastic and bend to the desired shape.
