I made a left and right hand skeleton, and added a 3/4 'plug' at the base for inserting into 3/4 PVC piping, which is what I'm using to construct the body for my halloween props.
these were created from the scanned skeleton hand from lambchops on thingiverse

I have printed these with no supports and 0 percent infill, but it's hit or miss on success. I would suggest some infill and supports.
