A friend had a couple of golf ball retrievers that had aged and deteriorated. They liked the performance but of course were broken beyond functionality. 3D printing to the rescue. As the design proceeded we realized the assembly could be printed as one pre-assembled piece. Other features included a flared pin to hold the inner ring from falling out and a hex recess for accepting a nut for the mounting screw. To get  a good pin some sacrificial supports were developed that were removed after printing.

The assembly was designed in SolidWorks and printed in ABS.  The Maker community has requested it be posted to Thingiverse. That is the plan but if you’re itching to try it you can download the .STL here. It is also the signature application for a Maker event at the Cumberland Business Incubator Labville.
