Here is the Fidgety Python for all who like to fidget and make shapes.
Please post pictures of your prints - especially if you use multiple colours.
IMPORTANT: This design has some pretty tight joints when it is taken off the print bed. For perfect results, ensure that your filament is tuned (https://wiki.bambulab.com/en/software/bambu-studio/calibration_flow_rate). Use only a 0.4mm nozzle. I'd recommend PLA only, and stay away from silk variants. The size of the print CANNOT be scaled down because of the tight tolerances in the joints.
When freeing the joints for the first time, I recommend using the sharp edge of a table to support the snake while you put pressure on each joint. They will all free up, but it will take a little effort. It's worth it!
A shorter version of this model, which takes less filament and less time to print, is available at https://makerworld.com/en/models/65617#profileId-68947
