Modeled in Creo Elements Direct Modeling Express- a relatively new FREE solid modeling program with a LOT of functionality. I'm surprised the community hasn't picked up on it very well yet, as it is quite good- I highly recommend it.
Process the .stl through your software of choice and print. I recommend a high fill setting for maximum strength. Sanding and/or reaming may be required depending on your printer's resolution and tuning.
