I wanted a flexi rex skeleton but I couldn’t find one already made, so I made this.

Began modelling by altering the original STL file but found it easier to start again, so re-made it from scratch.

It printed successfully without supports with these print settings:
   • 0.16 layer height.
       ◦ Smaller layers make printing the overhangs easier. It may need supports if printing thicker layers due to the steep overhangs.
   • Print wall order, inside to outside
       ◦ Helps support the overhangs as each wall supports the next one out. 
   • Brim to keep all the pieces held down.
