Shigaraki Hand Adapter
thingiverse
This is an Adapter scaled to fit the Large version of JS-Studio's Thing Hand from the Addams Family. https://www.printables.com/model/7804-addams-family-thing/files There is a recess to allow for your choice of glue, as well as a good portion of wrist from the Thing print. I designed it personally on Sketchup, and then threw it through a couple of file conversions to make a printable STL file.
