Quick modification to the inner lock ring of svideo's great DeWalt AirLock compatible twist-lock fitting. You must print the other two components from the original Thing files.
The original version is designed for certain models that have the lock groove closer to the end of the tool-side fitting. This works great for a variety of hand tools, sanders, etc. Unfortunately this design didn't work when attempting to connect to my DeWalt DWS780 miter saw, even though DeWalt touts this as a standardized fitting. The lock groove on that saw is further from the end of the tool-side fitting, which then interferes with the dog teeth on the inner lock ring. This is a quick-and-dirty modification to trim the dog teeth back to allow extra clearance.
