**1/30/2021: Updated to support a 1/4" threaded rod. I haven't been printing a lot lately, but I had need for one of these. These should work for Prusa remixes. Good luck and I hope you find these useful. Created in Creo Elements.
**5/19/2015 Updated EricCouplerRev3-5x5mm.stl for 5mm motor & 5mm threaded rod, M5 nut dimensions estimated. This should work for i3 machines and any other fine 5mm rods. let me know if the nut needs to be modified.
11/4/2013 v4.2, 6mm: Beveled the unsupported edge for the 6mm nut, Beveled the m3 Nylock grub screw hole and narrowed it .2mm, for a tighter fit. Please let me know if you need any other mods.
9/1/2013 modded v4 ->4.1: 6mm version for better 6mm nut fit and widened grub for a nylock nut. removed opposing grub and widened body to 22mm
8/26/13 Added 6mm and 8mm versions Bridged with a second opposite grub on the 5mm motor shaft.
