Excellent! This is most impressive, considering the difficulty of the task, how much further along have you gotten? Have you successfully attached it to a motor shaft? Did it hold up?
Also, when you say 'glue', do you mean resin?
My first test of the long coupling was disappointing. Not sure, but I suspect my vice causes a slight bit of slanting when I press fit the part to the shaft.of the motor.
Earlier, I mounted it in my lathe with a length of threaded rod and everything war perfectly round. Maybe I should just drill out the M5 side, and use glue, instead of press fitting.

The key is to print it slow. Let me know if you try this. I'll try it myself before the new year.
I have posted both 5/16" and M8 versions.
