About this model

This is a remake of my self-centering z-coupler ( The thread is now optimized for 3D printing and the overall length is way smaller. It's also a parametric design, so i can easily generate different sizes. I made 4 different sizes for 5mm motor shaft and 5, 6, 8 or 10mm threaded rod. You can just ask me, if you need different sizes. ---------------- 12/24/14: Added coupler_5_12, coupler_6_12 and nut_12 ---------------- 10/17/15: Added [V2.5] coupler 6.35/8mm + nuts ---------------- 12/16/15: Added [V2.5] coupler 5/3, 5/4, 5/7 + nuts ---------------- 02/04/16: Added [V2.5] coupler 5/6.35 ---------------- 03/12/16: Added [V2.5] coupler 5/5 ---------------- 05/26/16: Added [V2.5] coupler 5/8
