Another test with a joint connection

Here I used a cylinder to make the joint.

When it works I could make a chain with it...  In Cura  View Mode layers it looks all seperated.
The big problem can be the overhang because I can't build support between the 2 parts of the joint..

After the problem with the clogged extruderhead I could continue with this test.  After 16 minutes and 2% done it seems that the problem is over and the system is working fine...

And here after 57 minutes and 43% done.... It looks quite good.  A new problem will be the closing of the round parts.....

And after 1:53 hours it is ready.  And if works.
