Jason McAvoy Portfolio – Introduction to 3D Printing and Design

Hello

My name is Jason McAvoy. I am a 21 year old senior at James Madison University, getting ready to graduate in May 2019. My major is Sports and Recreation Management, and right now I am spending a good amount of my free time applying for jobs in the industry all over Virginia and DC. At JMU I am involved in Catholic Campus Ministry, and my I enjoy going to UREC and meeting friends at DHall for dinner. I am a huge Boston sports fan, but my greatest sports memory is being in DC outside Capital One Arena for the clinching game of the Stanley Cup last year when the Capitals won. My favorite TV show is Seinfeld, and I am almost done with watching The Office from beginning to end for the first time. I am also a stand-up comedian, I’m relatively new to it but I’ve done a couple of open mics in the DC area. My hometown is Warrenton, Virginia, and my favorite thing to do when I’m home is catch up with friends and go to El Agave, the best Mexican Restaurant around. I have no experience with 3D printing but I’m excited to learn something new in my last semester of college. Go Dukes 🙂

Thingiverse Model

https://www.thingiverse.com/thing:908561

I chose this model because I like giraffes and I lived the rigid design of this one and how it looked sitting down.

Thingiverse Print

The giraffe turned out good, with the exception of the chin, which was a little frayed. I think this was because the face juts out from the body. Otherwise I was happy with the way it turned out.

20 Forms in Tinkercad

(from top left) green cube with rounded sides, a blue cube, gray dice, orange cube, red isocahedron, blue sphere, and my name Jason in red text in multilanguage font

(from left) I scribbled my initials, an eight sided purple cone, a red rounded roof, a pink half sphere, a twelve sided polygon, a ten sided parabaloid, and a torus which I made brown too look like a donut

(from left) bright red diamond, brown ring, orange tube, red rectangle with a hole in the shape of a star, teal heart, tan peace hand

Tinkercad Print

Didn’t turn out like I wanted, I should have made it smaller so I could have printed it during class time and not had to cut it short. I also bent it a little bit because it was almost impossible to get it off the printer.

We had some mishaps with the first draft, namely the bottom was not smooth and it was hard to get the pieces to fit together. We slowed down the print speed for the final draft and added some supports. The final draft turned out much better, I’m happy with how it looks.

Fusion 360 Print

I printed a coin display for people who collect coins. I got the idea from remembering a silver dollar coin that we had in our house. It turned out well, but I would need to make it bigger for coins bigger than a penny.

20 Forms Fusion 360

For the first ten or so designs I stuck to making just regular 3d shapes, playing around with the size and dimensions

Played around with some cutouts and holes in the objects, and put a screw design on the outside of a cylinder

Fusion 360 Vase Design

i used a zig-zag pattern around the base, and staggered the second and third levels so there would be a curvature to it to give it a cool design. I was careful to not to make it too steep so that it would print out without any trouble.

Fusion 360 Vase Prints

Overall I like how it turned out, if I had to do it again i would make it taller and thinner (in terms of the width of the base). I liked how thin the wall is and how fine the edges are.

20 Forms in OpenSCAD

wrote OpenSCAD and adjusted the height to make it 3 dimensional

started with a cube and doubled the height to make it a rectangle

cylinder: played around with the number of faces so it would have a jagged look rather than a more smooth look

3 sided polygon, increased the angle so it would widen at the top

sphere, changed the resolution so there would be more faces

just started with a cube and played around with the dimensions

copied from adjusted the height to make more visible, resolution

polyhedron (copied from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube )

taken from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube, then adjusted radius and twist to get more of a spiral effect

rotational extrude (from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube), then increased the radius and convexity

changed the dimensions so there would be a bigger hole in the middle, less faces than the previous one

key design from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube

minkowski from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube, adjusted radius and height of both shapes

from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube

intersection from https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#cube, changed radius

OpenSCAD Print

Lifesaver, came out well and it helps that the filament was white. The size and roundness of it makes it look very realistic.

Overall I enjoyed this project. I’m glad that the idea came from something in my life that is an inconvenience (the cupholders in my car not being the right size for the bottles I use sometimes), and trying to make something that could solve this problem). If we were making these for actual use we would try to have more exact measurements, but overall they turned out okay. We also realized they could be used as a coaster.

Reflections and Future Projects

I greatly enjoyed this course. It was fun to learn something completely new in my last semester of college. My favorite things that I printed were a model of Fenway Park (my favorite baseball stadium), and the Washington Monument. In the future I would love to 3d print a ship (since I love the water), or maybe learn how to do a more detailed version of Fenway or another stadium or a monument or something like that since I love traveling and sightseeing.
