v3 - Updated, screw threads on Jefficus' threaded rod were backwards on one side, probably why it was so hard to screw in originally.

v2 - After shearing off the original threaded rod for this model I modified the part so it would fit inside of the collapsible handle without being too long. The mock up image of the original device is a bit deceptive as it doesn't show any of the threaded rod sticking out from the handle. This helps prevent you from trying to overtighten the part. The shorter screw thread section goes into the collapsible handle and the longer screw thread section goes into the scratcher head.
