Introduction

In this article, we will be discussing the design and optimization of a trip attack coin featuring a binary question. We will examine the issues faced with the initial design and the improvements made in the second version. Additionally, we will analyze the dimensions of the coin and discuss the necessary filament changes. We will also delve into the process of modifying the G-code and printing the final version of the coin. Finally, we will address the sound issue associated with the coin and explore potential alternative solutions.

The Design of the Coin

Version 1 Issues

The initial version of the trip attack coin faced several issues. Firstly, the first layer of the coin appeared unsightly, with visible holes during bridging. To rectify this, a wider edge was added to provide better stability for the bridging process. Secondly, the lettering on the coin was difficult to read due to the lack of contrast between the text and the coin's color. Lastly, the most significant issue was the weight of the coin. It felt too light and did not provide the satisfying sense of throwing a real coin.

Version 2 Improvements

To address the issues faced in the first version, several improvements were made in the second version of the coin design. The wider edge was added to enhance the quality of the first layer and provide improved stability. Additional graphics were included on the top and bottom of the coin to not only enhance its appearance but also provide more support for the bridging process. A hole was introduced to allow for the insertion of a screw washer, making the coin heavier and providing a more realistic feel when thrown.

Analyzing the Dimensions

When analyzing the dimensions of the coin, it is essential to consider the optimized layer height of 0.2 millimeters, which influenced the design choices. The height of the "No" text on the coin is 0.2 millimeters to align with this layer height. The coin consists of three layers of covering, followed by a hole for the washer. The washer's height is 2.4 millimeters, and an additional three layers of covering are added, totaling 0.6 millimeters. A filament change is necessary at a height of 4.0 millimeters to differentiate the "No" and "Yes" texts.

Modifying the G-Code

To modify the G-code, a text editor can be used to search for the "M600" command, which denotes a filament change. In the modified version of the code, the second filament change is replaced with a stop in printing, as there is no need for a color change at that point. By making these modifications, the printing process will pause to allow for the insertion of the washer, and then resume seamlessly.

Printing the Final Version

After modifying the G-code, the final version of the coin can be printed. The three initial issues have been successfully addressed, resulting in a better first layer, legible text, and a coin with a satisfying weight. However, one issue that remains is the sound produced by the coin during rotation. This issue has yet to be resolved, and input from readers regarding potential solutions would be greatly appreciated.

The Coin's Sound Issue

One area of concern with the trip attack coin is the sound it produces when rotated. Even with the addition of the washer, the sound remains minimal. This sound issue presents a challenge, as it is unclear how to solve it through 3D printing techniques. Suggestions such as utilizing CNC milling machines or experimenting with brass or steel filament types have been proposed, but these options may not be easily accessible to everyone.

Exploring Alternative Solutions

The sound issue surrounding the trip attack coin remains unresolved. However, there may be alternative solutions worth exploring. Readers are encouraged to share their ideas and suggestions in the comments section. By collaborating and sharing knowledge, a solution to the coin's sound issue may ultimately be discovered.

Conclusion

In conclusion, the design and optimization of the trip attack coin with a binary question involve multiple considerations. By addressing the issues faced in the initial design and implementing improvements, a more satisfactory end result can be achieved. Analyzing the dimensions and modifying the G-code are essential steps in the printing process. While the sound issue remains unresolved, the trip attack coin serves as a unique conversation piece and prompts further exploration into potential solutions.
