The Mad Cobra
A variation of the Grab Toy ++ (https://cults3d.com/en/3d-model/game/grab-toy) that turns 180 degrees. For this I needed to determine the length of the longer arms on the right as a function of totalArmLength (which is the lenght used for the left side). Since those arm lengths are not the distances between the axes of the hinges there is a bit of math to do (line 324 of the OpenSCAD file), but that's pretty much it.
To finish it up I added some text for decoration.
TheMadCobra(): generates the Mad Cobra model.
Included STL file:
