Resized crankshaft

This is a remix of the crankshaft from the air powered radial engine. The original design had an issue with binding in the housing. This is only a resized version which is a better fit, and not altered in any other way. It was resized in Matter Control version 1.7.5. I recommend using a hex head bolt with a nut to press the hex head into the plastic to form a hex shaped opening. Version 2 has the hex head opening. Version 3 has a hex head opening with a continuous round top for extra strength & less air leakage. Versions 2 & 3 were modified in Solidworks by our good member PSomeone. Thanks for his effort to help improve this design.
