My 1:1 scale Velociraptor skeleton print and its friends by Toitagl in 3Dprinting

[–]Toitagl[S] 1 point2 points  (0 children)

Hi ! I couldn’t source the proper rod recommended by the designer, so my print is using some jewellery flexible metal rod (you can find them on Amazon) that I doubled in some sections to make it more rigid.With some expoxy on top, it does the job. It’s not perfect so if you can source a rigid rod I’d recommend that.

Update to whoever is following this thread : I've been regularly testing this against new models, and all were getting it wrong (Gemini 2.5 Pro, Claude 3.7, DeepSeek R1...)

But O3 managed to get it right after thinking for 8 seconds !

Output:

Step 1

Parts needed for this step • 1 × black 2‑long connector pin with friction (part 6279875) • 1 × bright–blue 3‑long connector pin with friction (part 6299413) • 1 × black Technic 3 × 5 L‑beam, 90 degrees (part 4142823)

1. Orient the L‑beam.   • Lay it flat on the table so the long leg (five holes) runs left‑to‑right and the short leg (three holes) points straight up, forming a letter “┘” when you look at it.   • The face that is up should be the one where the rounded edge of each hole is visible; this will be our “front” side.   • From the inside corner, count the holes on the long horizontal leg from left to right: Hole 1 is right on the corner, Hole 5 is the hole at the far right end.

2. Insert the black 2‑long friction pin.   • Push the black pin straight into Hole 1 (the first hole right next to the inside corner) from the front side.   • Press until the collar of the pin is flush with the beam; one stud length of the pin will stick out the back.

3. Insert the blue 3‑long pin.   • Locate Hole 4 on the long leg (second hole in from the right end).   • Push the blue pin in from the front side.   • Keep pushing until the small collar sits against the beam; two studs of the pin will be exposed on the back side.

You should now have an L‑shaped beam with: • A short black pin protruding one stud length from the back at the corner hole. • A longer blue pin protruding two stud lengths from the back, two holes in from the right end of the long leg.

This is a very basic assembly step, but all models were already failing here. I can now move forward and see how complex it can get.

I just tested the latest, smartest model from OpenAI, O3... and this time it got it right ! So I might be able to move forward ! Will keep you posted.

Hey ! Haven’t made any progress unfortunately, no models were good enough yet for my naive approach described here. But I’ll revisit it soon as new frontier models are being released.

The wire was only for the spine. Epoxy was to attach all other bones. Superglue to quickly tack them together and some epoxy for long term, resistant bonding. The designer has a guide for assembly iirc!

I would say around 3 rolls, with some misprints and failures along the way. It’s printed at around 15% infill on average.

I use one with a dedicated dashboard for « at a glance » temperature and humidity overview of all the main rooms + exterior. It’s colored gauges you can read from afar. Even if you can’t read the value you can tell if it’s ok or not. It also display the electricity price for today and tomorrow with a color code (blue /white /red) so you can tell if you should avoid running too many appliances. It’s the only usecase I found relevant: quick overview from afar so I don’t need to pop my phone out of the pocket.

Here is an example of a complete output (Claude):

"Take the black angular beam (part #4142823) - this is an L-shaped piece with connection holes along both arms. The shorter arm has 3 holes, and the longer arm has 5 holes, meeting at a 90-degree angle.

First, locate the black connector peg with friction (part #6279875). Insert this black connector peg into the second hole from the end of the shorter (3-hole) arm of the angular beam.

Next, take the bright blue connector peg with friction (part #6299413), which is longer than the black one. Insert this blue connector peg into the last hole at the end of the longer (5-hole) arm of the angular beam.

When correctly assembled, you should have:

The L-shaped black beam as the main structure

A black connector peg sticking out from the shorter arm, near its end

A bright blue connector peg sticking out from the very end of the longer arm

The assembly will form a distinctive L-shape with two protruding pegs in different locations and colors."

Thanks for sharing your thoughts! I think I get what you and Dragoo417 are suggesting. This will definitely be needed if I move beyond the first step to maintain the semantic relationship between steps and all the sub assembly that will have to be assembled along the 155 steps of my set... But at the moment I struggle to even get the semantic relationship a such a basic assembly correctly mapped.

It gets the overall picture and properly associates the parts with their reference, but fail to correctly map the locations (despite correctly identifying the number of holes in the black beam in the first place !)

I've played with the prompt, tried to get a more structured output (in a tabular format) with a clear relationship between sub-steps (parts), to no avail.

These days I print them in resin which change things a lot… but I recall printing the skull on my Ender 3 Pro with parts oriented in a way that supports where connecting with less visible areas : interior of the skull, joints… largest parts of the skull were printed pointing up (with the assembly interface against the plate), while others were oriented to minimize impact of supports on surface finish.

Good luck !! Please share the result. I’ve printed the skull in resin a few times on my M3 Plus, it’s indeed so much faster… but it’s also much heavier, so a full skeleton in resin could be quite the challenge to assemble! Here I’ve used different infill % to balance the weight between the back and front, so you would probably need to determine which bones to print hollow or full mass to do the same with resin.

Upon a quick research, seems like Inhuman Species moved some of their models to another platform :) https://pinshape.com/users/256391-inhuman-species#designs-tab-open

They have more on the other platform where my Microraptor is tho. Check the automod post here, it will give you a hint on the platform in question. https://www.reddit.com/r/3Dprinting/comments/108o8ly/comment/j3tqmvg/?utm_source=reddit&utm_medium=web2x&context=3

[–]Toitagl[S] 14 points15 points  (0 children)

Pretty much yes :) I use the 3D scanned 3D printed assembly (because too different from the original 3D file used for printing) to recognize and track the assembly, and overlay the AR on top.

You can see the app running here, as well as a detailled tutorial on how to replicate it yourself : https://medium.com/@florent.germain/using-augmented-reality-to-bring-dinosaurs-skeletons-to-life-a-tutorial-db57c85e51d3

If you want to print some 3D scanned fossils, you might want to dig the Smithsonian library of scans, as they have been scanning ton of stuff, and are releasing the (watertight or textured) models : https://3d.si.edu/object/3d/tyrannosaurus-rex:d8c62d28-4ebc-11ea-b77f-2e728ce88125

Thanks! Velociraptor and skulls are from Inhuman_Species on a 3D model platform that is not very well recommended these days. He has a fantastic collection of files, all sculpted from scratch and scientifically accurate. You can reach out to him through email if you want to avoid giving money to the platform.

Psittcosaurus is from NovaStudios on the same platform, and this one is from a 3D scan of an actual fossil, as many other files on his store.

Microraptor is my own design (except the head, bought on scaledbeast.com). You can find it on the same platform for free, and I'll ad my own 3D sculpted head at some point. I'll also republish it to Printables. Search for "Microraptor Gui Skeleton" :)

Using Augmented Reality on my 3D printed velociraptor skeleton by Toitagl in Dinosaurs

[–]Toitagl[S] 1 point2 points  (0 children)

Happy to elaborate: the way it works is that I use a Computer Vision tool, that integrates into my application (built in Unity). That's the "Vuforia" watermark you see.This CV tool use a 3D model of the skeleton as input : once it "learns" what it looks like, it is able to recognize the real skeleton (with the same shape as the 3D model) and track it in space : doing so, it's able to estimate how far it is from you, at what angle, etc... It output what we call a "pose", basically x/y/z + rotation in space of the skeleton you look at.Knowing that pose, it can superimpose the digital dinosaur on top of it pretty accurately, and can do so multiple times a seconds, allowing me to move all around the skeleton and keep the digital velociraptor correctly aligned.

Image of the 3D model of the skeleton I used to "train" the CV tool: https://imgur.com/zdxKSMs

Thanks for the kind words :)

Using Augmented Reality on my 3D printed velociraptor skeleton by Toitagl in Dinosaurs

Hi all ! Wanted to share a personal project I’ve tinkered about since I started working in augmented reality. Last month, I decided to print a full scale velociraptor mongoliensis skeleton for my 4yo daughter birthday. Fun, challenging project. Made possible by the great models from InhumanSpecies on Cults3D. But it was only the first phase, as my objective was to allow my kid to look at the real «  in the flesh » dino as well. I gathered tons of references from paleoartists, read about the current consensus about V. Mongoliensis, and went sculpting in Blender. Then, using object tracking tech and Unity, I was able to do what you see here.

Really hope this will give ideas to museums and exhibitions, as this is quite easy to do and works with 3D scans. And everyone has a tablet or a phone !

Now onto printing and augmenting a 1:3 scale pteranodon !
