I printed LOVE23DPRINT's Flexi Rex for a friend and immediately got asked for MORE - but found out that they didn't always print reliably, the smaller parts coming unstuck from the bed and shifting about ¼ of the way through the print.
I didn't want to add full supports so tweaked this slightly with just some very small (1mm) strips on the tail that are very easily snipped or snapped off after printing.
Examples are printed in Polmaker PolyLite PLA Starlight Neptune which seems to work really well for this model.
The author remixed this model.

Added very small linking pieces to aid reliable printing
