SMA Barrel Wrench

SMA Barrel Wrench is a handy tool for tightening and loosening SMA connectors on cables in cramped spots. It's usable with most any plain cable with a straight SMA connector, as long as it doesn't have a strain relief boot larger than the hex portion of the connector. It doesn't work with right-angle connectors, or with most attenuators or filters.

This handy little tool fits in a pocket, purse or tool drawer, and it's perfect for engineers, technicians, hobbyists, amateur radio operators, and tool fetishists.

Please note that you might need to touch up the inside of the connector with a needle file to get a good slip fit. I may be able to adjust the interior dimensions a bit in a future revision, but I would like to get a better feel for the manufacturing variations in this 3D printing process before I tweak the design. Please let me know how this tool works out for you!
