This is the print-in-place version of the fidget snake: https://makerworld.com/en/models/63513
There is files for Snake with 4, 6, 8, 12, 24 sections.
I recommend printing the shortest one first to check for any issues with movements.
Additionally, you can print a key box (last profile) to facilitate the easy unplugging of the corner segments of the snake.
Tested it with Bambu Lab PLA filament on P1S printer.
