If you create a derivative work of this model and release the modified version on the Printables platform, you might as well link directly to the same model on Printables.Model number 46241。

The following is information from the old version. We suggest you go directly toGitHub page, check out the latest content there.

This model is a recreated version based on Airfish.Thingiverse project: 2189652)for Kirbs's Flexi RexThingiverse project: 1759297This is another optimization and reconstruction made by Zheng3. The original model of Airfish was likely inspired by Zheng3's "Flexy Rex".Thingiverse project: 929413)。

When I was printing the original model of Kirbs, I found that its hinge structure was slightly fragile, and one connection broke after rough handling. To address this, I comprehensively reinforced the connection structures of the handle, significantly enhancing its overall strength. This means that compared to the original model, this model can even be printed smaller without compromising the user experience due to weak hinges. Of course, you can also freely enlarge or reduce the model size as needed.

License Information

If you plan to sell this model to others or use it in public places, please be sure to visit the new version page on GitHub to review the detailed license instructions.

In short:

• This model adoptsCreative Commons—Attribution—Share AlikeThe agreement has been released. Please strictly abide by all the terms of the agreement. As long as you comply with the licensing conditions, you don't need to apply for additional permission from me. For the interpretation of the agreement, you can refer toYou can find my understanding on my GitHub page——For me, you just need to follow this interpretation.
• If you modify this model for non-personal use, you must do so in the same way.CC-BY-SAAn agreement, or a more stringent license agreement, to publicly release the modified model files.
• Even if you sell the printed copies of this model to others, you don't need to share the profits with them. Of course, if you want to express your gratitude to the creator, you can always send your thanks through the "Tip the Designer" button.
   

If you purchase a print of this model from someone else: if it's printed with high-quality consumables, the material cost of this model is only about $0.7. Added to the electricity bill and the possible depreciation cost of the printing equipment, the total cost will be no more than $2. If someone pays much more than this price for a single print, they are undoubtedly being overcharged.

This model does not require the addition of support structures. To ensure the strength of the hinge, I adopted a 3-layer outer contour line design - this approach is more reliable than simply relying on increasing the filling density to enhance strength. If the filling density is too high, the overall balance of the model may be affected due to the heavier weight of the head. If you want to further improve stability, you can select higher filling density for the leg components as needed.

After the model is removed from the build platform, it should be able to move smoothly and freely. If you spray a mold-releasing spray on the glass platform for printing, and the model is cooled and demolded, Rex will sometimes pop up on its own and assume various random poses. If you still need to forcefully pry it when unlocking the hinges, then there may be room for improvement in your printing process.

The printing difficulty of this model is not high. If you fail to print this kind of model for the first time, you will inevitably encounter similar problems with other models in the future.

There are some minor formatting issues with the text on Thingiverse, but I don't feel like fixing them anymore—after all, the content on this website often malfunctions unexpectedly.
