What it does

  • Articulates head to tail. 35 segments, all printed at once.
  • Reinforced hinges hold up to handling. Not a one-print fidget.
  • 8 g of PLA. Lives easily on a keyboard tray.
  • Designer credit: DrLex on Thingiverse, CC-BY-SA.
  • Ships in 3 to 5 business days. Free reprint if it arrives flawed.

A T-rex you can pose. Body, tail, jaw, and limbs all hinged. Comes off the printer fully assembled and starts moving the moment you free it from the build plate.

The trick is the link geometry. DrLex's reinforced version uses thicker hinges than the original Flexi Rex. The joints survive a kid's pocket and a desk drop. Articulation runs head to tail in 35 segments.

Original design by DrLex, licensed CC BY-SA for commercial print. About 8.0 g of PLA. Ships in 3 to 5 business days from our US printer network. Free reprint if it arrives flawed.

538k downloads in the maker community. That is interest in the design on the site it came from, not our sales.

What you get

  • This design prints as one piece.
  • Nothing else to print or buy for this to work.

What it is made of

Designs like this print well in PLA. Compare the materials.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
