Hey, I am Hannah Wilton-Jones and I am from Alexandria, Virginia. I’m a sophomore accounting major and I am thinking about also minoring in computer information systems. In my free time I enjoy reading, hanging out with my family, loving on my dogs, going to the beach, and watching sappy movies with my friends. Next semester I will be studying abroad in Antwerp, Belgium and I hope to spend most of my free time traveling and experiencing various different cultures. I also am involved in my sorority Kappa Alpha Theta. I don’t have any experience with 3D printing, but I am excited for the skills I will pick up from this class. I am not a very artistic person and I struggle with creativity, so I am also excited for how this course will challenge me. (Also peep my chihuahua in the bottom right haha)
“Pineapple Key chain” By tomdavid
I decided to go with a small pineapple key chain for my first thingiverse assignment. It will be useful because I need a new key chain for my house key and I thought it was super cute. I love it because pineapples remind me of the beach and summer. My roommates and I have cute pineapple designs all over our apartment and they just make us happy.
I would say that my pineapple key chain was an overall success. I struggled in the beginning with knowing which support options to select for my model. The initial problem that occurred with the first print attempt, was that the bottom of the pineapple base wasn’t sticking to the platform. This resulted in the pineapple to shift across the platform and the printer to continue printing over the same space where the base of the model was no longer standing. In the second attempt to print, the base of the pineapple stayed in place and it was successful.
20 Forms in Tinkercad
I used the hole, align, ruler, and work plane tools to create my 3D objects. In the first screen shot I have a coffee mug, a triangle bird house, a heart cookie cutter, a pencil holder, a ring, a bowl, a Christmas tree ornament, and a park slide. In the second screen shot I have a “H” key chain, a dog collar, a donut, a strawberry, a crescent moon, a star cookie cutter, a snow cone, a traffic cone, a tissue box holder, a flower, a house, and a heart shaped charm.
I would say that my first tinkercad print was both a success and a failure. I think that I was successful in learning how to import a model file from tinkercad and complete the print on the 3D printer. However, my first try at tinkercad designs could use improving. Initially when I created my 20 forms I was unaware you could import designs from thingiverse, so my first designs using tinkercad were very basic. I think that this print could’ve been more creative, and if I could do it again I would create a tinkercad model with more “wow factor” for this assignment.
Summary of Group Tinkercad Project
Wiener Dog project with Grace Howard
I really enjoyed this project because I think it was challenging for both Grace and I. I will admit our final model and print didn’t look like how we envisioned the dachshund design in our heads, however, after a lot of work and tinkering and reshaping our tinkercad model I think we improved a lot from our first day. We are both not as skilled in using tinkercad, but we learned a lot from this project. I also think that we chose a difficult figure for our first design project because a dachshund is a rounded, nonlinear, and curvy 3D figure to design. Therefore, it was hard to make our model look realistic, but we definitely gave it our best effort.
20 Forms in Fusion 360
10 points, due by noon on Tuesday 4/2
- include screenshots of your 20 forms, in groups of 7-10 objects
- briefly describe the designs in your screenshots and how you made them
- try out as many Fusion 360 tools as possible
- use Tutorial page and/or YouTube tutorials to learn more tools
(Sketch, Extrude, Pipe, Sweep, Fillet, Loft, Constraints, etc)
Fusion 360 Print
For my fusion 360 print, I tried to design a small unique paperclip holder for my desk. I wanted to use the loft and offset plane tools to make the form more funky looking than just a simple hollow cube. I think that I was successful in printing a cool looking 3D form, however, after holding it in my hand I feel like I went too far out with the spline tool because the print turned out really fragile and thin. Next time I wanna try and do it by lofting two 2D star planes.
Fusion 360 Vase Design
For the 3D vase design, I started out by creating a circle by hitting “sketch” and “ctrl C”. Then I added two off set planes, one on top of the other, by using the “offset plane” tool under the “construct” tab. Then I went into the “sketch” tab again and clicked on the “spline fit” tool to draw trace out the outline of my vase structure. This tool was really cool because it allowed me to shape my vase model with defining curves and crinkling.
Once I had finished using the spline tool on both of the offset planes, I used the “loft” tool listed under the “create” tab. In the “loft” tool I was able to connect all three planes together to form the 3D vase by selecting the outlines I made with the “spline” tool.
In addition to these modeling instructions shown in the video, I also decided to add extra curving and a unique twist. I also wanted to make my vase different by having the top plane structure fan out, making the top of the model the widest. Fortunately, I was successful in doing this without spreading the top out too thin or breaking my model by twisting it too much.

Finished (large) print:
I think that my 3D fusion vase was a success. I’m really happy with how it turned out. I think that the curving and wide shape of the vase is really unique and I had a lot of fun with the lofting tool. I’m hoping to find use for this light weight vase in my apartment, and so far I’m thinking about using it for a plant.
20 Forms in OpenSCAD
(I apologize I couldn’t screenshot more than 5 objects together on my laptop)
For my first figure, I used the rotating tool in the code to rotate 3 same sized cubes to make this cool pointed sphere. In the second figure on the top right, I used a code from thingiverse of a thin ring model which I altered to make a donut looking figure. I changed the inner radius of the circle and the height of both inner and outer rings to make the whole look smaller and the figure more thick and rounded. Next, for the figure on the bottom left inspired by a thingiverse design, I was able to create a rounded rectangular prism by adjusting the radius dimensions of two 3D cylinders coded inside a 3D rectangle. I made the star using the coding example we used in class and plugged in the dimensions that I wanted. On the farthest right, I made a pyramid inspired by a thingiverse openscad example. I altered the thingiverse code by putting in my own dimensions to make it look more like a pyramid.
For the figure in the top left, I used the openscad cheat sheet to create a code that makes a parabaloid and I played around with the dimensions to form a bowl type of shape. In the bottom left, I created a sphere by referring to the openscad cheat sheet. I increased the $f by a lot to make the figure look more rounded and sphere like. By playing around with the number of $f I lowered it to make a christmas ornament looking type of sphere on the bottom middle. I then used the information on coding a cylinder from the openscad cheat sheet to create a simple wide cylinder. Then by adjusting the bottom circle radius to zero and keeping the top circle radius=10, I was able to create a cone figure which I thought was really cool.
On thingiverse I found a model that was coded to make a 2D pizza slice on openscad, so I used this model to create a thick deep dish slice of pie by taking the 2D shape and using linear_extrude and increasing the scale and height as well as its other dimensions. Then using this same triangular 2D shape I created a 3D guitar pick by using the linear_extrude tool and thinning and fanning out the dimensions and scale. On thingiverse I also found a really cool model that had rotating stars inside of a circular enclosure. I decided to alter the code by increasing the number of points to the stars and rounding out the edges so that they looked more like rotating flowers which I was really impressed by. Next, I used the “sphere ();” code again, but I made the $f number=2 to make a 3D triangular prism. I realize theres probable other ways to create a triangular prism, however, I’ve found the sphere code to be really useful in making many different models. Then I found an openscad design on thingiverse of a really thin and wide pipe looking figure meant to represent a part of the human knee. I took this model and decreased the radius of the inside circle so that the pipe rounded together more closely. Then I plugged in different dimensions for wall thickness and height to make the figure more rounded and thick so that it looked like a macaroni noodle.
I had a lot of fun with the last 5 figures I made. I found a youtube tutorial for the lego block figure in the top left picture. For the lego figure, I had to download a code that was already made because it was a very complicated design, however, I changed the dimensions of the lego piece to make it only a narrow 3 bump piece. It took a while to figure out how to use the lego code, but I felt accomplished when I finally did. On thingiverse I found the bottom two designs for a nut and bolt on thingiverse, however, I increased the number of faces and splits to make them have 6 edges and hexagon shaped. The middle top figure was made using the youtube tutorial from class and is probable my favorite design. I also used the sphere code and f$ as well as parts of a egg thingeverse code to create the easter egg on the farthest right.
Here’s links to sources I have used for this project:
I decided to print the Lego piece I made by altering the dimensions of a openscad code I found on thingiverse. I think it was a success because it printed exactly how I wanted it to look. The only thing that might be problematic is that the bottom of the lego piece isnt perfect. The design incorporates a cut out of the bottom which makes it look like the piece could function as a real lego piece and be connected together with another piece. However, it doesn’t actually look perfectly cut on the bottom once it is printed because the 3D printer isnt precise enough. So, I’m thinking that it might be harder to print a functional 3D lego piece than I thought.

OpenSCAD LEGO Ring with Grace Howard
Thingiverse link: https://www.thingiverse.com/thing:3583229
My partner and I made a customizable LEGO ring in OpenSCAD altering a single piece LEGO block code and writing additional code for the ring and customization parameters. I thought this was a really cool final project and I’m proud of how successful the project turned out. It was difficult in the beginning to come up with a project design that altered the LEGO code enough to show our understanding of such a complex code as well as adding out own code to it. We were able to successful meet our goal of being able to attach different LEGO prints to our final print rings and I was excited about that. If I could do it again, I might add coding that lets you add two rings to wide LEGO block parameters so you can wear larger pieces across your fingers with more stability and room for more attachable pieces.

Reflections and Future Projects
In this class, one of the things I was concerned about was being able to come up with creative designs for my assignments. I definitely think the 20 forms assignments were the projects I struggled the most with, however, they tested me to really force myself to be creative. I didn’t always do well on the uniqueness of my 3D forms, however, I’m still happy about the effort I put into it as well as the skills I learned from using all the different software. Also knowing myself and how bad I usually am with things like art, design, and creativity, I feel like I have improved from this course. If I could’ve done anything differently, I would’ve tried to print more cool thingiverse models and posted “makes” because I think its really cool that students and people of all ages are able to share their designs and see what other people use them for.
In the future, I plan on finding cool customizable openscad deigns that I can print using my own parameters. I also would like to possibly print one of the jewelry dishes our classmates designed because I thought they were really cute! I will be here for Maymester taking a class, so I’m hoping I find time to 3D print again after this semester. Even if its just a small key chain or monogram print, I think it would be awesome to be able to take advantage of the free 3D printing in Carrier Library.
