***UPDATE 1/12/2012***
Added .PK2 and .STL for 4mm stepper shafts
***EDIT** Rev2, I made some adjustments to the columns and verified that the .PK2 file works in Creo again. I printed a new one and it looks better than the first one I uploaded. Let me know what you think. Use EricCoupler2 for the newer version.. I also found Thing# 12190, which is really similar, he made his first so I've listed this as a derivative though I created mine separately before I saw his.
This coupler came from my seeing and experiencing issues with other couplers. I wanted a Z coupler that was round and would not snag any loose wires. I wanted one that I would not have to worry about slippage, and that would be beefy. After a little experimentation, I decided the captive nut idea was the best. This is my first posted Thing, so Comments are certainly welcome. I design objects with PTC Creo. It's awesome. Elements is Free.
