..........................................................................................

Update: 9/17/2025… More neck joints added. Each dino needs 4 small pieces and 4 large pieces totaling 8 when assembled. I try to make the 3mf plug and play, but sometimes I do miss things. On the prior project file there were 5 small and 5 large neck joints which is only enough for one. I have added 10 small and 10 large because I personally like to print extras!

What do you do when you can't figure out how to make a Flexi Brachiosaurus neck that's also poseable? Well...you engineer a new mechanic. 🦾

After doing a crazy amount of test prints getting that neck just right, I couldn't be happier with the results. The shorter back legs and more upright head position differentiate the Brachiosaurus from the Brontosaurus, and makes it the largest of the Sauropods! I have to admit I had to research a bit to learn about the differences hahaha.

As usual, I created two head versions (with and without the eye), a stand, and since this Dino is an herbivore, A little branch it pulled from a tree. Keep your eyes open for the XXL post coming Wednesday. 👀

When Putting the neck together, make sure you separate the large and small joints first. Pay attention to the slot orientation, and snap together 4 large on the bottom, and 4 small on the top. And the neck looks amazing because of the way it prints. You can get a very similar effect to multicolor with just a gradient!

*Caution: Just like building blocks, they can be hard to get apart once you snap them together.

Happy Printing -Dan

Print tips and Info:

• STL and 3MF files are included. * If you use the 3mf file, please remember that it is a painted project file for your convenience. You must check your material/printer/settings to make sure it works correctly for your printing project.

• I print with .12 or .16 layer height for quality.

• As usual, make sure you have good adhesion, especially for the mini versions. A glue stick works or I have switched to using on all my machines... a BIQU Cryopgrip Frostbite adhesion plate.

• Consider a brim if you have concerns about the links losing adhesion, they have a small footprint. And print more than you need :)

• I successfully test printed between 50% and 370% XXL for this design.

• XXL version must be GLUED together with Super Glue.

• Gradient PLA works well with this model: I have a comprehensive list of Filament I use here: Amazon List
