PS70: Intro to Digital Fabrication

<div class="textcontainer"> <p class="margin"> </p> <h1 style = "text-align: center;">Week 2: 2D Design and Cutting</h1> <br> <p class = "margin"></p> This week, I learned how to CAD on Fusion. I have experience working on other CAD softwares such as Solidworks and OnShape so transitioning felt relatively minimal. That said, it was my first time applying my CAD skills to a laser cutter, which was a fun learning experience adjusting to the new tool. <p class = "margin"></p> <br> <h2 style = "font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;">Designing a Box</h2> <p class = "margin"></p> The concept of my box was inspired by a combination of a dice and the Mrs.Potato Head Toy. In other words, I wanted to animate a simple box with human features incorporated into the design. Feet, ears, nose, and lips. <p class = "margin"></p> <image style = "width: 40%" src = "2.1.png" alt = "Character Design" class = center> </image> <br><p class = "margin"></p> I drew out the flattened schematic of the box, lid, and the remaining body parts. This was used as a guide for the CAD. <p class = "margin"></p> <image style = "width: 80%" src = "2.2.png" alt = "Sketch" class = center> </image> <br><image style = "width: 80%" src = "2.8.png" alt = "Mrs.Potatohead Nose" class = center> </image> <br><p class = "margin"></p> However, I soon realized that I liked the box better without any facial features so I decided to keep it blank. <p class = "margin"></p><br> <image style = "width: 100%" src = "2.6.png" alt = "Mrs.Potatohead CAD" class = center> </image> <br><p class = "margin"></p> Through the first iteration of the box, I realized that I could scale the model up so that I could fit more into the box. I increased the sides of the box from 10cm to 15cm while keeping the remaining body parts and slots the same as the previous iteration. <p class = "margin"></p><br> <image style = "width: 70%" src = "2.3.png" alt = "Character Design" class = center> </image> <br><br> <br><br> <h2 style = "font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;">Fusion 360 Tutorial</h2> <p class = "margin"></p> In addition to the box, I was able to further excersie my CAD-ing skills on Fusion 360 through following an <mark2><a href="https://www.youtube.com/watch?v=YDCnFoE_lZ0">online tutorial</a></mark2> walked me through designing a bottle cap. Seemingly simple, I know from prior experience that knowing how to thread and clone ridges is an essential skill that is regularly used. For this reason, I found this video to familiarize myself with these tools on the software. <p class = "margin"></p><br> <iframe width="100%" src="https://www.youtube.com/embed/YDCnFoE_lZ0" class = center> </iframe>  <br><p class = "margin"></p> Final drawing: <p class = "margin"></p><br> <image style = "width: 100%" src = "2.4.png" alt = "BottleCapFinal" class = center> </image> <br><br><br> <h2 style = "font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;">Modeling Assembly</h2> <p class = "margin"></p> The last compenent of this weeks' assignment was to apply our CAD skills to everyday objects, with the goal of creating an assembly out of these objects. I decided to draw out a case for my airpod pros on Onshape, the CAD program I'm most familiar with thus far. First, I able to retrieve precise dimensions of the object by a combination of open sources measurements online (for curved surfaces) and on my own with a caliper. <p class = "margin"></p><br> <image style = "width: 80%" src = "2.7.png" alt = "Airpod Schematic" class = center> </image> <p class = "margin"></p> Due to various curvatures on the airpods, drawing out the case became a bit more complicated than expected especially since the case needed to fit perfectly around the device. I ended up duplicating the shape of the airpods, scaling it up around the original sketch and shelling it (adding tolerance). I split the hollowed out case at the line of the opening of the airpod case, and added additional features such as the keychain hole and charging port separately. Finally, I took all the parts to the assembly tab (my first time using this feature on Onshape) and put all the components together in a relation such that the airpod case slides on and off of the airpod sketch. <p class = "margin"></p> <br> <image style = "width: 80%" src = "2.11.png" alt = "Airpod caliper" class = center> </image> <br><br> <image style = "width: 80%" src = "2.9.png" alt = "Airpod" class = center> </image> <h2 style = "font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;">File Access</h2> <p class = "margin"></p> For access to my drawings for this weeks' assignment, please download the zip file linked below! <p class = "margin"></p> <p class="margin"> </p> <div class="flexrow"> <a id="btn" href="./Week 2.zip" download> Download My Files </a> </div> <p class="margin"> </p> <br><br><br> <image style = "width: 20%" src = "Design.png" alt = "End Pic" class = center> </image> <br><br> </div>
