Took the fantastic model from @GraemeH_223680 and expanded the holes to fit some rods I found on Amazon.

The author remixed this model.
I made the holes slightly bigger on both the top/bottom part and the arms. The arms might be a little too tight, I had to force them down the rod, but they move just enough and I don't have to worry about accidentally changing their orientation.
