January 2026: FlexiDinos fancy Ginko the flexi Brachiosaurus
It's got feathers, I tried to make it look like Dmitri Bogdanow's illustration on wikipedia whích I used for reference but as spikes would have been hard to print I made feathers. Happy new year to all of you!.
Currently I'm working on the FlexiDinos full time because I lost my job. I love to design these toys and I'm trying to make a living out of this. So if you like my models and can spare some money please consider joining my club!

December 2025: FlexiDinos Günther the flexi Stegosaurus cookie puncher
I wasn't happy with the reindeer-Ankylosaurus model, so I came up with something else!

December 2025: FlexiDinos Gregor the flexi Reindeer Ankylosaurus print in place articulated dinosaur
EDIT: This model sucked. I have removed it and won't publish it again.
Fresh from the gene-labs, I mixed up some Reindeer DNA with an Ankylosaurus.

November 2025: FlexiDinos Jerry the flexi furious T-Rex print in place articulated dinosaur
EDIT: I noticed I made a mistake. I thought it was funny to increase the models size by 10 % to make it more frightening. But as I plan to release the Lego adapter saddle soon, this doesn't make sense as the saddle wouldn't fit so I undid it again. The correct version of Jerry is v10.
A little too late as every month here it comes: A Tessa limited edition with an angry face. Available only here in November 2025.

October 2025: FlexiDinos Spoopy the flexi Zombie Parasaurolophus print in place articulated dinosaur
this model took a little more time than my usual model of the month, so I decided to put some more time in the description as well. I had so much fun doing it I'm thinking about zombifying some more of my dinos over November.
He's got a Glasgow smile, his guts are hanging out and there are many more details for you to discover. I hope you like printing it as much as I had fun developing it. Happy halloween and happy printing as well!

May 2025: FlexiDinos Filip the flexi Parasaurolophus print in place articulated dinosaur
This one was very simple. No frills, a few gimmicks with the lateral position to get the joints all in the right position and that's it. So that it doesn't get too bland, I've added movable legs. As with all my models where it makes sense, it is designed on a scale of 1:100. It therefore fits all my dinosaurs except Dimetrodon and Pterodactylus.
To keep things interesting I want to play with it a bit over the next few evenings because the plan from the start was to integrate a whistle into the head, but Christmas is just around the corner and you all want to print the new member of the herd, don't you? And let's be honest: do we really want the kids to have a new dinosaur with a built-in whistle to play with over the holidays and drive us crazy with it? You're welcome.
I will post updates on the model in the next few days if the whistle works. Maybe I'll also add movable front legs, who knows. I'll definitely give it a try, it all depends on what comes out of it.
Edit 21. 12. 2024: It works now and I've just uploaded the whistle files!
That's it for now, Merry Christmas and have fun printing!

April 2025: FlexiDinos FINAL VERSION: Tessa the flexi T-Rex print in place articulated dinosaur
It had to be done! The free version of Tessa the T-Rex isn't perfect, but I'm here to fix it. I sat down and made some improvements. I fixed the tongue and the jaw hinge, and I also fixed the legs. There were a lot of little details that separate an okay model from a perfect one, and I'm happy to say that I corrected them. Here is the final version. If you find any problems with this model, please let me know and I'll be happy to fix them and make it even better. This means that it can be updated in the future if someone finds more things to improve.
I also brought it to scale 1:100, which means it will fit all the future versions of FlexiDinos I create!

March 2025: FlexiDinos Karli the Flexi Dimetrodon print in place articulated dinosaur
It's everybody's second favorite Mohawk this time.
Wonder who everybody's favorite is? You're welcome. Don't do drugs. M'kay?
My wonderful Club Members chose and I followed their call. User DirkvK took inspiration by my models and published his own version, which you can get here for free!
Designing the Dimetrodon
But here's mine, some details about the design process as usual: I quickly decided that this model would be printed on its belly, as getting the sail right would be the main challenge. I used the same idea as for Gregor the Ankylosaurus. When I designed him, I thought it should be possible to make the whole hinge inside the body to reduce the gaps as much as possible. To achieve this, the diameter of the body would have to match the diameter of the hinges. But this was impossible with Ankylosaurus' curvy physique so the Dimetrodon was the perfect choice to give this idea a try.
To give the sail a bit more stability, I added some extra hinges on the same axis as the main body. They're a bit fragile, but I guess it doesn't matter if they're there or not, so I'll leave them for now. I'm sure I'll be updating the model in the near future as there are a few details I'd like to fix. But why should only big computer game companies release their unfinished stuff? Maybe it will be a collector's item in a few years. You're gonna be rich!
Print instructions
I printed the prototypes in Prusament PETG, which had quite an impact on the last models I designed due to its high bed adhesion. It allowed me to get very small parts sticking to the build plate, which caused quite a problem when I switched to PLA. So I pulled myself together and made large flat areas on the underside of the model. PLA should be no problem here.
The sail is the weak point of this model due to its thinness, so it might be a good idea to raise the printing temperature a bit if you want it to be strong.

February 2025: FlexiDinos JJ the Flexi Velociraptor / Deinonychus / Utahraptor print in place articulated dinosaur
AHH! Fresh meat!
It's everyone's favorite combat chicken. At 100% scale it's a 1:100 Utahraptor. So you can scale it to 50% to get a Deinonychus (not recommended with anything over a .25 nozzle and even that didn't give very satisfying results) or to 25% to get a velociraptor which totally makes no sense at all. They basically look the same.
I even watched a cockfight (Schwanzglied anyone?) on youtube to get in the mood to design this beast. Something I can't recommend to anyone because it's stupid, unnecessarily cruel, and surprisingly boring in the end. Since this was a dead end, I had to use my own imagination, like a caveman or something. Ugh!
So let's talk a bit more about the Schwanzglied. The last three joints on this model are designed to look like a peacock's tail. This is because the main design process was done in just two night shifts. I can't stand living an easy and happy life, so I decided to give myself a challenge by throwing away the whole tail design and managed to come up with something a bit more challenging for me as a designer and also for your printer as it is only attached to the print bed by a very small area.
This cost me the better part of last weekend where I had some time without my wife and kids and otherwise would have come up with stupid ideas, (I built this slingshot a while ago, hurt myself badly on the 3rd try and just rediscovered its a lot of fun to shoot it if you know how to use it) so its probably for the better for everyone. Thanks Deinonychus!
So far my printer has managed to get it out in one piece even in PLA but I recommend printing this in PETG as it has much better bed adhesion.

January 2025: Gregor the flexi Ankylosaurus print in place articulated dinosaur
Strike and Maim!
(See here for instructions on printing and finishing)
An all time favorite for everyone who thinks Triceratops is mainstream: The good old Ankylosaurus. Where its thagomizer reaches, nothing remains. Designed for battle, but also practical for major renovation work, the Ankylosaurus is a welcome guest at any demolition party.
Just some quick design notes, you can see the whole design process here if you want to dive down the rabbit hole. Since this is a very wide dinosaur, this model had to be designed without the usual approach of it lying on its side. So I had to come up with a way to print it on its back and still have a curved shell on top. It took me about three weeks to come up with the first two joints, and I didn't know if they would work, so you can imagine how happy I was when they finally did.
This model is a show piece. So if you want to impress your 3D printing friends, just show them the back of this model and tell them you sawed your print bed into 3 pieces to get this result or something :D

December 2024: Klaws the flexi Santa-Pterodactyl print in place articulated dinosaur
It's a bird! It's a plane! It's Klaws! Half beard half pterodactyl it brings the presents and eats them.
Fresh from the gene lab, I fused Santa's DNA with some pterodactyl juice from an old coprolite, and poof - here he is. Meet Klaws, part prehistoric chicken, part old guy who ate too much of it and still somehow manages to fit down the chimney.
You may have noticed that this is a variation on Bertha the Pterodactyl, but it's for club members only, so if you can download it, please do: Thanks a lot!
I didn't even forget to put a hole in her pom-pom, so you can hang her in your Christmas tree this year. Hooray for that! And Merry Christmas to you all!
Disclaimer
I can't stress this enough, so I'm going to write it down here: FlexiDinos are in no way suitable for small children. Parts can break off and leave sharp edges, so make sure your children are old enough to know what they're doing before letting them play with FlexiDinos!
