Nina Coughlin Portfolio


Hi, my name is Nina Coughlin and I’m a sophomore at James Madison University. I’m from New Hope, PA but my family moved to Ambler, PA my first year of college. I have a black lab named Otis and an older sister who is featured above on the right named Casey. I’m majoring in Health Service Administration but have no idea what my plan is in the future for a career yet.

I have no experience in 3d printing, so my Goal of this 3d printing class is to explore. I think this is something I can tell my friends and family about and it’ll open my eyes to a new experience. I’m excited to learn something new and out of my comfort zone and I think this course will let me be creative.

Thingiverse Model

Title: Butterfly Ornament

Designer: MikeT71


I chose this model because it was simple. I have a weird obsession with butterflies. This specific model has holes within the design so I can put it on a keychain if I wanted to.

Thingiverse Print

I think I had success within this project. My object came out well and I’m happy with the result. I didn’t run through any problems, so that’s good.

20 Forms in Tinkercad

  • Pink Heart with N was made by using the heart shape and the letter N. The N was made into a hole and then grouped together
  • The paw print was made with the scribble tool and the cylinder, then all grouped together.
  • For the eagles design, I uploaded an image.
  • The smiley face was made with cylinder and two cylinder for the eyes. I turned the eyes into holes as well as the smile made from the scribble tool. Then grouped them all together.
  • Purple cone thing was made with two shapes and grouped together.
  • I wrote my name with the scribble tool.
  • The green dice tool with a cylinder as a hole. This could be a bead.
  • Uploaded a butterfly image for the pink butterfly.
  • Four leaf clover is made with four heart shapes and the stem is made with the scribble tool.
  • I used the star shape and then the exclamation point as the hole.
  • Purple rectangle has a shape grouped inside.
  • Blue pyramid looking things started as the diamond shape, but the height changed.
  • Darker blue shape started as a sphere and has a cylinder inside as a hole.
  • The pink thing on the right started as a sphere and changed the radius, etc.
  • The dark pink both started as different shapes and I morphed them and grouped them.
  • Letters P & A grouped together because I’m from PA.
  • Half sphere put inside a shape like a bowl.
  • Olympic rings made with the ring shape.
  • Cylinder stretched and shortened and put “hi” in the middle.
  • Made a face with a cylinder, mustache, and glasses.

Tinkercad Print

I think the print was a success. If I were to change one thing, I would have made the steps more intense so the circle was more round.

Summary of Group Tinkercad Project

20 Forms in Fusion 360

  1. I used sketch to draw a rectangle, then I used fillet to round out the edges. Then I extruded it to 20 mm high.
  2. Sketched a line then sketched an arc. I then extruded the arc and used the shell feature under modify. Then I moved the object so it was laying on its back.
  3. Made two lines and used the parallel, equal, and coincident constraints. Then after the four lines were connected by using the constraints, I extruded the object to become a box.
  4. I created a cylinder (pipe). Then I edited a hole into the center by right clicking and then pressing “hole”, I made sure to make the length of the cylinder and the hole the same.
  5. For this object, I took the above directions then used the “shell” feature.
  6. First I sketched the circle, then I sketched the polygon on a different plane. I then used the loft tool to create the object.
  7. I created a coil insert, then changed the roundness to a triangle shape. Then decreased the size by using the toolbar.
  8. Created by using fit point spine. Then I extruded only one section of it and deleted the other part.
  9. I created a sketch, then a line. I added and arc and used the revolve tool. I then changed the degree to 180 so it created a half circle.
  10. I did a sketch and then used “inscribed polygon”. I then used the shell tool under modify to create the hole in the middle.
  11. Sketched a rectangle, then extruded it. I then created a circle and lofted the two with the circle in the center using 3 profiles.
  12. I sketched three lines together to make a triangle then extruded it.
  13. I sketched three lines together to make a triangle, extruded it, then used the draft tool to make one side angled.
  14. I sketched a square then extruded it and used the chamber tool to make all the dimensions around the sides.
  15. Sketched a circle, extruded it. Then created a hole in the center.
  16. I did the above steps, then created a thread within the hole.
  17. I used the fit point spline tool to sketch the waves, then I extruded them.
  18. Sketched two circles then lofted them using the loft tool.
  19. I created two circles like above and used the loft tool, after that I used the draft tool to create a cone.
  20. I created a box with two holes in it.

Fusion 360 Print

  • Overall, I think this print was a success. The only issue is that the holes aren’t aligned properly, but that could be fixed in Fusion360 using constraints.

Fusion 360 Vase Design

  • The first screenshot is of the top view of the 3 profiles before I lofted them. Then the second screenshot is after the 3 profiles have been lofted together, and morphed slightly to change the spiral of the design. I used the red line to change the curve of the vase and make it less basic.
  • My final design goes beyond the basic design shown in the video because this design came uniquely from me and my crafting. Although the 2nd and 3rd platform designs are similar in shape, I think that makes the more difficult to change the shape of the vase. I managed to change the shape by using techniques such as change the spiral, making this vase more detailed than the one shown in the video.

Fusion 360 Vase Prints

  • I personally thought this print had no specific failures. I think I could’ve done more to it to make it more intense, but other than that I think it printed well and there are no distinct failures. The major success of this print is that I didn’t have to reprint anything.

20 Forms in OpenSCAD

  1. I copied the code for Poly Bowls and changed bodyTwist to 150, bodyFlare to 1.5, sides to 8, diameter to 50.
  2. Made a cube connected to a cylinder.
  3. Made a cube and a cylinder under a “difference” to make a hole within the cube so it’s only part of the cube.
  4. Made a square true to the origin but made the sides so it looks like a rectangle. I also changed the color to pink.
  5. I used the rectangle from above. I then added a circle and changed the color to blue. Then I rotated the circle 60 degrees.
  6. Made a sphere with a cylinder in it.
  7. I used the above sphere and cylinder but defined different height and widths to connect the spheres and cylinder to create a rounded triangle.
  8. I used union between two cylinders and rotated one cylinder 90 degrees and true so it was in the center.
  9. I did the above steps, but used “difference” to make a hole in the cylinder. I also made the radius smaller on the second cylinder so the hole was smaller.
  10. A made an oval using scale and resize on a circle.
  11. I made a sphere then did difference to make a hole in the middle with a cylinder.
  12. I made a ring by doing rotate_extrude and translate in a circle.
  13. I used linear_extrude with a twist on a circle.
  14. I made a cylinder with different parameter to get a cone shape.
  15. Used an import from Thingiverse to make a star
  16. Used the above import and changed the parameters.
  17. Imported heart code from Thingiverse.
  18. Used 20 sided polygon to create this bowl shape changing the height and extrusions to create the walls.
  19. Made cylinder in weird heights to make a cone.
  20. Created 3 different cylinders with the same dimensions but rotated one 90 degrees and the other -90 degrees.  

OpenSCAD Print

  • I don’t think there are any failures within this print, but that could also be because this is a fairly simple print. My overall thoughts on this print is that it turned out well, but the designing process on OpenSCAD is genuinely difficult to understand because I’ve never coded before.

Summary of Group OpenSCAD Project

  • Nina and Kara’s Ring Holder Dish with Kara Hines
  • Thingiverse
  • Group OpenSCAD
  • The project was overall enjoyable. We got to be creative with our design and create something we can use on a daily basis. It was also really cool and exciting to see that someone else made our make on Thingiverse. I think Kara and I worked really well together and got to overcome the challenges as a team. We had one problem of not being able to use the bunny stl, so we compromised and changed it to a cactus.

Reflections and Future Projects

  • Although this course required a lot of out of class work, I genuinely enjoyed it. It was satisfying to learn a new technique and tool for the future. I liked how much freedom we had in this class to design and print whatever we wanted. A lot of my work created in this course was very basic, and didn’t accurately show how advanced the 3D printing world really is. With more practice and detailed work put into the designs, someone has the ability to create something amazing.
  • Now that I’ve been exposed to all the different types of 3D printing sites, such as Thingiverse, TinkerCAD, and OpenSCAD, I have the ability to use all these sites to create anything. I don’t know anything specifically that I would make with 3D printing, but it’s definitely something I will always think of as an option. The 3D printing world has endless opportunities, and without a doubt it will come up in the future. Whether or not I’m printing something, I believe the topic is important to learn about. I know people use 3D printing in the world of energy to create tools for saving energy. In my case, there really won’t be a specific time I can think of where I will use my knowledge of 3D printing.
