Tube It In was designed by Wil Strijbos and it should come as no surprise that it was originally made in metal before Eric Fuller released the wood version in 2016 on Cubicdissection.
It’s hard to believe that I’ve had this puzzle for 3 years now. Eric just released another batch of these for 2019, prompting me to pull mine back out. Although, I stored mine in the orange sash that it came in, it was easy to locate by feel due to its diminutive size and shape.

It takes a little more effort to pack the tubes back up, but it’s not that difficult. My attack plan, as with most packing puzzles, is to start with the biggest pieces first and work my way down to the smallest. It took me about 5 to 10 minutes from start to finish.
I originally had a description here of my experience packing the first 5 pieces together, but I got the "What! You're telling them how to put it together?" response from my wife, who convinced me that what may seem obvious to me may not be obvious to others. This is certainly not a mistake I would want to make right after a new set of puzzlers receive their copy of Tube It In. Sorry, you're on your own now.

The new version that Cubicdissection recently offered has magnets that hold the two largest pieces together, which is a nice addition, although I think it would have been even nicer if the magnet hadn’t been exposed on the outside when assembled. I also like that the wood selections for the different tube sizes have been altered so that you can easily identify the vintage of the puzzle.
