Cluster Puzzle (review and solving)

This puzzle was made last year, but because of war, I couldn't show it for you on this channel. It is easy for children and may be pretty hard for adults This is a packing type of puzzle It has two cover nuts 7 spacer rings with holes and pins and the main rod, with engraved rules Main task: you need to reassemble the puzzle behind marked line First step of solving - using gap in cover nuts One spacer can be used as a key We can hide one solid ring here In second cover nut we can hide spacer with holes It fixed inside, and thread screwed all the way Second step - using correct tread position of cover nuts In that position we have less space on a rod In that position we have more space on a rod Same logic with the second cover nut That's wrong position That's correct This two parts assembled behind marked line And now we just need to put this 5 spacers in this gap At first sight, this is impossible, but if you will "think outside the box"... The Cluster puzzle is solved :)
