CAD Assignment

For this project, I decided to go with something that is beginner friendly and something that I may be able to use. I asked AI for several ideas and I decided on creating a desk organizer that includes a stand for my phone since it is always laying around the desk not doing much.

I started with thinking about the things that i would like to put in the organizer (since I might print it out and use it)

A phone stand, a container for pens, a pocket for my AirPods, and a few more extra spaces for other things.

Left tall container -> for my pens

Center block: my phone stand (with my initials on it)

The rectangle at the right to the middle: space for my Airpods

Other spaces scattered around: for different little objects that I might need

Now that you have seen the entire organizer, lets break it down part by part:

The Blueprint:

This shows all the parts that were used to make the organizer. The main body is shown in 4 drawings, from the front, from the top, from the bottom, and an isometric drawing.

The Skeleton:

This is the skeleton of the dinasor, the bones of the organizer.

I created this by first drawing a sketch:

You can see here I have a lot of measurements.

  • I have an Iphone 15 Pro Max and I wanted it to stand: thats why I created the slot at the top of the drwaing with a 90mm length, so that the phone can fit in and still have a bit of space on the sides.
  • I have a pair of Airpods: so I gave him a big roon, with 65mm of length and 50mm of width.
  • I dont have a lot of pens: so I just created a container with a 58mm diameter so that I can fit 3-4 pens that I use daily.

Adding on the meat…

From the sketch comes the extrusion of the base of the organizer, with a depth of 10mm.

Then I extruded these 2 highlighted parts since I wanted them to come out of the organizer rather than sinking in.

Then I exturded this highlighted part. This will be te stand for my phone and I also extruded my initials (2mm dent)to add a bit more of customization.

I transformed the phonestand so it slants backwards and so that I am able to leave a room to put my phone in and having the stand as my back.

Fine tunning the edges…

These highlighted parts have been “fillet”/smoothed out. This makes the organizer safer (preventing cuts) and also makig it look a lot better than with sharp edges.

This is a close in picture of a fillet…

Adding on the scales…

What I mean by scales are the plates that I add under the skeleton and the meat. This is for filling the holes so that I could actually use the oragizer.

Without the scales:

With the scales:

I added the scales seperately because it looks pretty good from the bottom, instead of having just a flat base, I am able to have the plates sticking out a bit, kind of like little legs:

Assembly:

Assembly is where I put all of my parts together. I have 10 parts and in assembly I put them all together to create the final organizer.

As you can see here, I used sliders to connect the base covers to the base plate.

This is an example of a base cover that I use slider to mount onto the base plate.

Bill of Materials (BOM):

So as you can see here, I decided to make the organizer out of mostly PLA since it is an organizer and would need to be stable and long lasting.

I was wondering whether making the organizer entirely out of PLA would not look that great and not really unique from the other desk organizers I can find in IKEA or Walmart.

Then the idea of making the base plate (the Skeleton) out carbon fibber might be a good idea since I really like the sporty look of carbon fibber and it will look high end and modern.

I also wanted the PLA to be white so that I can have some contrast to the carbon fibber and it would look good since white goes well with black always.

Below is a picture of BOM with the mechanical drawings:

The Final Product:

This is an illustration of the final product in the materials that I would like it to be in.

I feel like it is pretty modern looking and it kind of reminds me of Channel.

I would definitely want to print it out and show it off to my friends.

    Excellent job, Jack! You have been thorough with meeting the requirements and clear with your explanation. I have a couple of design questions, but these don’t affect the assignment itself. The mates that you have created are slider mates. While I get that you would have to slide the base covers into position, they would ultimately be fixed, I assume. If they would be permanent once inserted, perhaps a fasten mate might be more appropriate? Also, I think that you intend for your phone to lean up against the plate with your initials on it? If so, I wonder what is preventing the phone from sliding and falling down. If you do want to print this and use it, you might want to fix that design issue.

      Hi Mr.Crompton, thanks for the feedback! For my bases, I did not plan to make them permantly inserted, so that I could remove the base whenever I want and I could clean them, so this is why I used the slider. The phone will not fall down because the height of the back board is high enough.
