Hi Bruce,
Yeah, the rounding was already there. I changed the length so the outer ribs end closer to the end.
I made a new test print, and found out I need to do some more work on it. The longer inner rib doesn’t fit well in the keyway. I’ll send some pics in a separate mail. And I think the inner diameter should be a few tenth smaller to get a snug fit.
By the way, this is on a relatively cheap $180 3D printer, so nothing fancy at all. A "Fabrikator Mini V2” from Hobbyking. I bought it to see what I could do with it, learn some new skills perhaps, and found out it is quite addictive. Resolution (vertical) was set to the highest setting which is 0.1 mm. It takes around 40 minutes to print.
Kind regards,
Ben
