This is a scorpion puzzle. It was originally designed for a laser cutter. I extruded it in Openscad. I did not design this scorpion just made it 3D printable. This puzzle and many others can be found at blechwelt.com/teil_des_monats/archiv.htm
The original scorpion is large. I wanted a small one that was more life size so I resized it. That is the one shown in the photo. Print one of the Part 1 plate and one of the Part 2 plate. I haven't printed the large version but, it should be about 150mm long. The small version is about 80mm long.
