This is how I created a resonating chamber stand for the resonating chamber of a velociraptor. Yes, I’m serious! 😀
As some of you may know, I’m a die-hard fan of the Jurassic Park films. My girlfriend and I have watched these movies together so many times that we know them by heart.
In the third part (Jurassic Park III), Billy Brennan (Alessandro Nivola), the assistant of Dr. Alan Grant (Sam Neill), creates a velociraptor resonating chamber using a “rapid prototyper”.
This is the scene:
I took me countless repetitions of this scene to realize that I have such prototyper at home! A modern one! An damn 3D Printer! Two of them meanwhile! 😀
So I searched the common 3D exchanges for a suitable model. I found what I was looking for on https://www.printables.com (big THX to @nick041696_2583519 for sharing). I printed out the model and was happy.
But after a while, I decided to put the model in my wall unit shelf. Unfortunately, the model doesn’t stand on its own because it is round on the bottom.
So I designed a model for a stand for the resonance chamber.
Modelling the resonating chamber stand in Fusion360
In summary, this is how I proceeded in Fusion360, to create the resonating chamber stand:
- Inserted the source mesh (Mesh – Tab -> Create -> Insert Mesh) downloaded on https://www.printables.com (stl file of the package)
- Create a sketch for the stand body
- Extrude all resonating chamber stand sketch parts by 15mm in the direction of the resonating chamber
- Since I realized, that the performance of Fusion360 was poor with the used source model and I didn’t needed such details, I reduced the mesh size (Mesh – Tab -> Modify -> Reduce) multiple times.
- At this point I became aware that the mesh of the resonating chamber was damaged. I got these errors:
– Mesh is not closed
– Mesh is not oriented
– Mesh does not have positive volume
So I had to repair the mesh by using the mesh repair tool of Fusion360 (Mesh – Tab -> Prepare-> Repair)
- To prevent the model from fitting too tightly in the stand later, I increased the size of the resonance chamber body by 0.2 units in each direction.
- Afterwards I used the combine tool to cut the intersecting part of both models out of the stand body (Cut-Operation). I preserved the original bodies and created a new result body.
- Finally I used the fillet tool to round all edges of the velociraptor resonating chamber stand with a radius of 5mm
- And finally finally, I realised that the source model (and hence the stand too) wasn’t placed in the right plane to print it properly (Z to top). So I had to rotate the source- and the resulting stand model around the x axis. Therefor I used the Move / Copy tool. This could have been done later in the slicer too, but I like to have ready to print orientation in my Fusion360 projects.
- La FIN
P.S.: After I published the model on https://makerworld.com/, another user revealed to me, that the resonance chamber is also an ocarina (musical instrument).
Models
Here you can find a preview of all involved 3D models. By the way, the rendering is done by babylon.js.
(Babylon Viewer). To have the models oriented properly, I had to reverse the rotation made in step 9 before exporting gltf, bin, obj and mtl files. In contrast to most 3D tools (at least slicer) Babylon Viewer uses the left-handed coordinate system approach with the Y-axis pointing up.
