The Fantastic Jack Puzzle

Some days ago I found this nice little puzzle Das fantastische Jack Puzzle! at the Youtube channel of Mr.Puzzle.

Though it seems to be at least 7 years old, I couldn't find this puzzle for my 3D printer. There are hundreds of "... 6 piece puzzle ..." or "...ball puzzle by Charles Perry..." published, but none of them uses the same logic! Also most of these don't use round sticks, that make the solution even more difficult.

The goal is to assemble/disassemble the sticks as shown in the pictures. To find the correct steps is not easy, but alone the skill to hold the parts in the correct position for the assembly is a challenge. For me this is another puzzle in the series "...I'd like to have more hands" ;-)
