This maker coin is designed to test the functionality of the 3D printer. It has a diameter of 6cm and a thickness of 1.25cm. The coin is designed to help calibrate 3D printers and see if they are working successfully, testing functions such as engraving, curved printing, different filaments, and a variety of other functions.
The image on the coin is based off of my initials as well as the logo for DC's Green Arrow.
The coin is embellished with the cool arrow logo in the center and my initials on either side. There are extruded cuts in the middle to add to the sleek effect. Around the edge, there are small quivers with the end of a arrow sticking out of them. There are a total of six (6) of these around the edge. There are also small gaps in the edge to allow for easy grip. The filament is a special transparent green, which results in the perfect Green Arrow green as well as an awesome effect. The coin incorporates many curves and edges to truly test the 3D printer, which is the function of its design.

Overview and Background
Inspiration for Arrow design on maker coin
Displayed above is the Green Arrow logo, which was the inspiration for my entire maker coin theme. Originally, I saw my instructor's maker coin in a cool green transparent filament color, and that led me to decide to do an Arrow theme. I am a huge Green Arrow fan, so that is mainly why I went with the design and theme I did. Then, I came across this picture, and I just knew that I had to use this for my arrow design. As a result, I designed my maker coin to have an arrow in the middle with my initials on either side for personlization. Below is my original sketch, which I will explain thoroughly.
Above is my initial sketch. As you can see, the arrow design is in the center. I was initially going to add my initials on top of an extruded circle. The "Z" would be on the left and the "C" would be on the right where the paper was ripped. The side was going to be sharp with indents for easy grip. As you can see, there are no extruded cuts in the middle of my initial sketch. I will now explain how this sketch evolved into the final product throughout the 3D design process.
If you look at the final product, you can see the same arrow design in the middle still. For my initials, however, I decided to extrude cut through the entire coin to make it more simple, but still just as sleek looking. I then added extruded cuts around the center arrow. The cuts were purposeful, to add more sharpness to the maker coin similar to the sharpness of a real arrow. The extruded cut at the top of the maker coin is in the shape of a bow.
For the edges. I decided to do six extruded cuts to result in six separate edges. Why did I choose to do six cuts? Well, in the Green Arrow from the CW show, he holds 24 arrows in his quiver, which is a multiple of six (6). As you can see, I am a big fan. On the edges, I circular patterned a cut to make it seem as a quiver was on the edges, and then I designed the end of an arrow and circular patterned that to make it seem as if an arrow was coming out of the quiver on each individual edge. This resulted in the final product you see in the real life photos. I was able to make a gear-like Arrow themed maker coin. The maker coin was a cool transparent green, and it functions as a maker coin should: To test various filaments as well as different functions of the 3D printer.
Also, I would recommend watching the Green Arrow Tv Show from the CW.
The arrow coming out of the quivers on the edges are a bit hard to see in the real life photos because they are small. If I were to redo my maker coin, I would make them more distinct to make it easier to see.
The Solidworks renders may not be the exact same color I used. The green transparent color was hard to replicate there, so I used a glossy dark green for the renders.
Lesson Plan and Activity
Create a Maker Coin that is representative of yourself and can be used to test out new filament in a 3D printer.
- All coins must be made from an initial revolve resulting in a coin that is 6cm in diameter and 1.25cm in thickness.
- Must have a flat bottom.
- Must slope downwards towards the middle in some fashion.
- Must be gear-esque in nature.
- No moving parts.
