FLEX puzzler

It's a puzzle or thinking game focused on creating shapes and solving challenges like the ones outlined in the following link: https://spelarch.vives.be/PDFspelregels/15569.pdf

It's a very easy and quick model to print.

You can make it as long as you want; in my case, it consists of 12 pieces, following the instructions of the 'FLEX Puzzler' game.

To assemble it, all you need to do is print the pieces and thread them with a rubber band, tying it on each end.
