Hi, my name is Brittany. I was born in New York City but moved to Livingston, NJ just after 9/11. I’m a senior here at JMU (I’m not ready to leave yet), majoring in Finance. After graduation, I’ll be moving back to NYC to start my dream job, which is working on a trading floor with Keybanc Capital Markets. When I’m not in school, you can probably find me out hiking with friends, shopping, snowboarding, or rewatching Gilmore Girls for the 80th time.
I have pretty much no 3d printing experience but I’d love to leave JMU being able to say I know how to work the machine and create designs.
Title: Skull Snowboard Stomp Pad
I chose this model because I love to snowboard and I think it will be really cool to be able to look down and see something I printed on my board.
I printed this stomp pad in a much smaller size than the designer intended on it being. I still think it was a success because the groves would make for really good traction on a snowboard. I do wonder if I could get the print to be smoother, like the designer’s image.

Item Descriptions (left to right, top to bottom)
- Mug – I used a solid cylinder and placed a hole cylinder in the inside, using the align tool to center it, then rotated a donut shape to make the handle.
- Target – Used a cylinder and adjusted the height so it would lay flat. Then, I centered a ring hole and grouped the objects.
- Ice cream cone – Placed a cone and flipped it. Then used the workplane tool to add the ‘ice cream.’ I added another sphere and used the ruler tool to size it, then grouped all the objects together.
- House – I started with a cube and placed the roof near it. I used the up arrow (when you hover over the object) to lift it and place it on the cube. Then I sized another cube to be more rectangular as the chimney.
- Shooting Star – Dragged a star onto the workplane and made a hole out of a ‘B.’ Then, used the scribble tool to make a tail and grouped them together.
- Ring – I started with a ring object then added a diamond next to it. After I rotated the diamond, I centered it and grouped the objects.
- Chanel Logo – Used a ‘C’ and sized it then used the duplicate tool to create an identical one. Next, I flipped one and added an elongated sphere to make the cutout in the middle.
- Butterfly – Click and dragged a butterfly object then used the scribble tool to make antennas.
- Flower – Made an oval shape with the ring object and made duplicates, rotating it every time a new now was added. Then added a half sphere in the middle.
- Christmas tree – Found a tree object and made duplicates before rotating them. Then used a workplane to add a snowflake on the top. Used the rotate tool to adjust and the align tool to center it.

- Mountains – I made a pyramid then made two duplicates. I used the ruler to adjust the height of the middle pyramid before grouping them.
- Box frame – Sized a cube into a rectangle then used 3 hole cubes to make the cutouts.
- Crown – Used a solid “wavy topped cylinder” then made a hole cutout of a regular cylinder before grouping. Changed the color of the object by clicking ‘solid’ and choosing.
- ‘Hi’ Thought Bubble – Chose the thought bubble before adding text. Changed the font type and made it a hole.
- Lego – Placed a rectangular object on the plane and added a cylinder. After correctly sizing, I duplicated the cylinder twice then made a rectangular cutout on the bottom.
- Cylinder with hexagon cutout – Used a regular cylinder that I changed the color of. Next, I made a smaller hexagon and centered it with the align tool before grouping them.
- Dimensional Star – Started with a star object then used the workplane tool to add the beveled star on top and then changed the color.
- Smiley face – Sized a cylinder so it would lay flat, then used the scribble tool to draw a smiley face. Sized the scribble so it would come up a little higher than the cylinder then grouped them together
- ‘1997’ Necklace pendant – Used the numbers 1, 9, and 7. Then, made a duplicate of 9 before moving them together and adding a ring in the center (using the align tool).
- ‘Brit’ Keychain – Flattened a rectangular cube and grouped it with a ring in the top corner. Then, I added text and changed the font before making it a hole. Used a heart object to replace the dot in the ‘I’ and made it a hole before grouping and changing the color of the object.
I think this was a successful print. The construction and thickness of the print was good. However, if I printed this again, I would adjust the ring size to make it smaller because the size of the ring makes it a bit more fragile.

Project Name: Potted Succulent (Link)
Partner: Becca Sullivan
It was really cool that we got to design and print a model of a succulent. We got to choose what kind of plant we wanted and what our pot would look like (actually funny because the pot ended up looking like a pot Becca has at home!). I was really lucky that Becca is such an amazing artist because she really nailed the succulent portion.
I really want to print a full size model to keep on my desk and when people ask where I got it, I can say we made it!

- Three tier cake – I started with a circle and used the extrude tool to pull it up. Then I made a smaller circle and did the same thing. I used the move tool to adjust the height of the new cylinder. Lastly, I made a cylinder and used the align tool to center the tiers.
- Pool – I started by making a rectangle and used the fillet tools to make it curved on the edges. The use of the shell tool made it easy to make the pool indent.
- Abstract shape – I started with an extruded triangle and I didn’t know what to make it into so I started playing with the tools. I ended up making another shape off to the side and used the draft tool and chamfer tool to make strange angles. Then, used the press pull tool them to different lengths.
- Rock – I started with a circumscribed polygon and the extrude tool to make it 3D. Then I used the draft tool to modify different sides of the shape. I used to appearance tool to change the color of it to a granite. There is a offset plane on top of the shape.
- B – Starting with a rectangle, I drew a line through the center and used the fillet tool (under sketch) to make one half of the bottom. When I did this, I had to make another line so I could do the same to the other side.
- Door Stop – Starting with a 3D rectangle, I used the filet tool (under modify) to create the slope. I then added a line to the top and extruded it so it would make kind of a handle. The physical material tool allowed me to change the color to red wax.

- I made a box and used the mirror tool to create the start of number 3. Then I made a cylinder near it. Using the chamfer tool I beveled one side of the box. Then I used the shell tool to split the cylinder.
- I started with a cylinder and made a hole in it. Then used the thread tool to make the cutout and add texture to the inside.
- This started as a mirrored box (from number 1) then I placed a sphere next to it and used the combine tool. I made a thinner box and adjusted the width to be 2.5mm because clicking and dragging wouldn’t work for that size. I moved them together and combined them.
- Starting with a circumscribed polygon on the plane, I used the offset plane tool to place a cylinder above it. Using the loft tool allowed me to make the strange form.
- I started by making a sphere and I used the scale tool to make it bigger. I drew a closed arc on the inside and played with the split body tool. From there I used some of the previous tools to mess with the side.
- I started by making a box and I used the hole tool to make the cutout. Using the fillet tool, I made the circular side cutout and using the chamfer tool I made the opposite edge.
- Started a new sketch with a three point rectangle. Then I made a three point arc on the side. Using the trim tool, I was able to get rid of the flat side of the arc. I used the fillet tool to curve the edge of the rectangle and the line tool to make a triangle (trim the bottom again). I used the revolve tool and changed the settings to ‘full’ and scaled it down so it fit better on the plane.
Item Descriptions Continued [Clockwise]
- Used a rectangle and played with the chamfer tool and fillet tool, then used the move tool (m) to make it so it was in the air.
- I made a two boxes, one large and one small. I used the move tool, only this time I used the rotate function. After combining them, I extruded one side.
- I made a cylinder and moved a box so it would sit on top. then used the fillet tool to curve the top two edges and the hollow tool to make the cutout.
- Starting with a cylinder, I used the chamfer tool to create a point.
- I used the sketch tool to add text then the extrude tool to make it 3D. I also changed the font.
- I used the line tool to made a jagged shape and extruded it. I played with the sketch tool to add another side to the shape and pulled that as well.
- Starting with a rectangle, I extruded it to make it into a box. Then, I added a Torus and another cylinder to make the cutouts. Then using the fillet tool, I curved the edge.
Fusion 360 Print
The design was made with the revolve tool so the final print was a circle with groves on the inside. The design was more or less successful. There was one part of the model that felt a little loose. If I had to do it again, I would maybe make the loose edge a little thicker to stabilize it.
Fusion 360 Vase Design
My final design goes beyond the basic design in the video because I created a unique shape using the fit point spline sketch tool for both the top and the bottom of the vase.
To start, I drew a design with the fit point spline tool. Then, by constructing an offset plane directly over the shape [shown in picture], I drew another shape with the spline tool. By using the loft tool, I created the solid form. Then I played with the shape of the sides. The above image shows the final design.
Fusion 360 Vase Prints
My vase print was a success. It printed well and had a cool design and shape to it. It also didn’t have any holes or gaps that made the print feel unsteady. I also thought it was really interesting that by using the spiralizer setting on Cura, the print time would be so short. I think my small print took 8 minutes and the large print took an hour and 45 minutes.

Figures 1, 2, & 3: I used the PolyBowl template and playing around with the specifications in the code.
Figure 4: I made a circle and square and used the translate, rotate, and union tools to make them overlap and joined.
Figure 5: I found a template online and was able to customize the code so that it said JMU DUKES on it. This code used the “if” “else if” function to define parameters for the angle of the letters.
Figures 6 & 7: were made using the translate tool to adjust the positioning of the objects.
Figures 8, 9, & 10: Figure 8 was made by taking a cube and a cylinder and using the difference tool to subtract one shape from the other. Using the same code, I switched difference to union so that the objects would be joined rather than subtracted. Finally, I switched union to intersection so that only the overlapping parts were kept.
Figure 11 & 12: Very simple designs but I wanted to play with the parameters of a normal cylinder by adjusting the top and bottom radius to see how the different ratios would affect the shape. As shown in the photos, adjusting the radius can determine which way the shape sits.
Figure 13 & 14: I used the tool ‘for’ and created a variable ‘i’ then used the rotate and echo tool to make a bunch of squares rotated around one another in figure 13 and rotate and translate for figure 14.
Figure 15: I used the difference tool combined with the translate tool to create a cube with a cylinder hole. Then I copied the cylinder code to make a larger hexagon shape.
Figure 16: I followed a tutorial on how to make a union between a cube and cylinder.
Figure 17: I made text then used the linear extrude tool to make the height = 2.
Figure 18: I created two cylinders… one with normal r and h variables and another with r1, r2, and h so it would create a sort of rim on the bottom.
Figure 19 & 20: I made a triangle out of a circle by setting the face number ($fn) to be 3. Then, I used the color tool to make it purple (figure 19). Next, I used the copy, translate, and the mirror tools to make a mirror image of the triangle.
The print was successful in that it printed without errors. It also successfully made the two holes with different depths. I will say that OpenSCAD was a lot harder to work with because I had no previous coding knowledge. I watched a lot of tutorials and I thought it was interesting to tinker around with the code to see what aspects of the model would be affected.

Project Name: Customizable Ring (Link)
Partner: Becca Sullivan
We made a twisty-ring that was customizable both in the size and the amounts of twists it had. The design process took a lot of messing around with but I think we got the code down for the most part. However, our printers made the ring a bit scratchy so I don’t know if we could actually use these rings. The design could be sent out and made into a real ring made of silver or better plastic.
Reflections and Future Projects
This class flew by. I wish this class was longer because I had a lot of fun learning about something I would otherwise not have exposure to. I went from never even seeing a 3D printer up close to knowing how to design and export my own designs on three different platforms. I really love the idea of pretty much having no limits on what we can design. I feel like this class was also just a lot of problem solving. There were cases where our design worked, but it could be improved–whether it was adding a little more stability by making the design thicker or changing the parameters of the actual print.
I don’t think there is anything specifically that I want to make in the future, but I do hope to have access to a 3D printer one day. I think it would be a really great skill to have and would allow me to customize objects for my family eventually.
