Project 2 - Building Object

The object I am recreating digitally for this project is this music box.



I started by disassembling it into all its separate components.


Most of the modelling was pretty simple, starting by drawing in 2D using measurements from the object. Then I was able to extrude the 2D drawings into 3D shapes. I did a mixture of building the shape of the object and building the negative shapes to subtract from the object.


For the "drum" of the music box, I tried giving it a different song. I used a website that works like a digital music box and found a song I liked.  I used a screenshot of the song and the "comb" I had modelled as references for where to put the bumps on the drum that hit the "keys" of the music box.


In order to get the 2D representation of the song onto the cyclical "drum" I had to first use the unwrap command  to get a flat plane the exact size of the outside of the cylinder. I then took the pattern of bumps that I modelled and used the flow along surface command in order to put them onto the "drum".


I would like to see if I can 3D print the "drum" of this model and put it in the music box in order to change the song.

Overall, I had a lot of fun doing this project and didn't come across too many issues, it just took a lot of time to make all the pieces. Trying to be accurate was surprisingly frustrating. I expected digital calibers to just measure everything perfectly and be a breeze but this was not necessarily the case. I was working at fractions of millimeters which was really finicky. Even just using more force on the calibers when measuring would give a different dimension. And the object being so small meant that even differences of fractions of millimeters were noticeable when trying to put all the parts together. Also I had no way of measuring the curves exactly so I often had to just eyeball them to the best of my abilities. 

Even when I was putting the physical object back together after disassembling it, it had to make micro adjustments of where the "comb" part was sitting in order for it to work again.

Week 12 - Test 3D Print

Image
 My test 3D print was medium successful. I was able to print the music box piece with no issues, but it doesn't play the song correctly. You can hear some of the song when you try to play it, but some of the notes don't quite work. I think the piece just required to much fin detail to be able to be 3D printed fully functional. Also because I modeled the piece based off of a digital music box similar that wasn't exactly the same as my music box I think the tune of the song is off. Printing this gave me a good idea of what the supports are like to use and remove from a model though, which gave me confidence to use them with my project. For the settings of my 3D print - Peter suggested I print with much a finer detail level (0.05mm) since the piece had a mechanical function.

Project 3 - Modeling and Prototyping

Image
I started out modeling the astronaut in blender using the references I drew. The model is composed mostly of simple shapes - spheres and cylinders - scaled and combined together. The hands and feet required more editing, using Blenders vertex, edge, and face editing tools, as well as extrusions and loop cuts to make more complex shapes. I started out just making the shape of the body, then later worked on each piece individually hollowing it out and adding any internal structures. My first 3D model of the astronaut was very simple, I just wanted to start printing quickly so I could get an idea of how the physical object would be put together and make changes from there. My first printed prototype worked really well but had a few issues. The elastic cord I bought to string the doll was too big, so I bought some smaller stuff and made the doll bigger for the next prototype. I was able to partially put the doll together with wire for the time being. I had also left out the notches on the
