Cooler Flexi T-rex remix

- Made some small appearance tweaks to the Benchy4Life's design. Might not be as close to the actual t-rex, but looks more like toy. (Updated: eye is bit different to the version on the photos: photo of latest version on thumbnail)

- 0.7 scale version on the pictures
- Print in 0.2-0.14 resolution, out of PETG (0% cooling) or PLA (100% cooling)
- I chose 40% conectric infill with 2 top and 2 bottom layers for this cool "muscle like" look.
