For this week’s assignment, I chose to print a Mercedes keychain using 3D printing. I’ve always admired Mercedes. it’s one of my dream cars, and creating something related to it feels personal and motivating.
The logo and brand represent elegance, power, and innovation, and I wanted to reflect that in a small but meaningful project.

Inspiration Image (Phone Stand Model)
For this week’s assignment, I chose to create a phone stand.
I found the design on the 3axis website and downloaded the DXF file from there.
I liked this idea because it’s both functional and simple. Creating something I can actually use on my desk felt practical and satisfying.
What inspired me was seeing how digital designs can turn into real, physical objects with precision using laser cutting. It’s simple, but the process made me appreciate how creative and efficient digital fabrication can be.

1- Choosing the Design
First, I chose the design for a Mercedes keychain (Mercedes cey chaine) from the Thingiverse website, which offers a large collection of open-source 3D models. I searched for a model that matched my interest and fit the assignment’s requirements.
2- Downloading the STL File
After selecting the design, I downloaded the STL file

In Ultimaker Cura, the first step I took was to add the 3D printer I was using
1- The printer is not an Ultimaker Brand, so, I selected: Add a non-Ultimaker printer
2- Choosing the Option: Add a non-networked printer
3- Searching for the printer
(Creality Ender-3 / Ender-3 v2)
I Searched for Creality Ender-3 / Ender-3 v2 and added it to the printer list.
3- Printer Added
Preparing The Design
Open the File (Drag and Drop)
I opened the STL file using Ultimaker Cura software.
I started with slicing the model to calculate key information such as the estimated print time, PLA filament length, and the final weight of the product.
Then, I adjusted essential settings such as layer height, print speed, and infill density (all of which were kept at their default values).
I also checked the orientation and size of the model, making it slightly larger to better suit the purpose and ensure smooth, efficient printing.
My favorite part of the process was using the Preview feature.
I carefully reviewed the printing path step by step, layer by layer, focusing on the infill structure and performing a final check to make sure all details were in place before printing.
Finally, I saved the project as a G-code file, and included all key details print time, weight, and filament length in the file name for better organization and tracking.
I opened the DXF file using LaserWork software.
I repositioned the design to the corner of the workspace to save material for future projects, I resized the design to ensure it was both useful and realistic, adjusting the dimensions to properly hold a phone.
To add a decorative touch, I imported a flower design (also a DXF file).
I resized the flower, then duplicated it and placed a copy on the opposite side of the stand to create balance.
I selected the flower outlines and set them to engraving style, customizing the color, speed cut, and power settings for engraving.

Mr. Doggy
In Week 1, our projects focused on preparing DXF and G-code files for both the laser cutter and the 3D printer.
For the laser cutting task, we downloaded a dog-shaped keychain design and made some adjustments to it, including scaling it to the right size for cutting. The main challenge we faced was with the engraving settings. We discussed how to set the speed, power, and intensity, but the engravings on the dog's body turned out very light.
This helped us understand how crucial it is to fine-tune the engraving parameters for better results.
When we got stuck, we turned to our instructors for guidance and also collaborated with each other as a team.
While working on the laser cutting project, we faced issues with the engraving. The design was downloaded, and we made some changes, such as resizing it. However, after running the job, we noticed the engraving on the dog's body was barely visible.
We paused and had to research the right settings for speed, power, and intensity to ensure engravings were properly applied. This experience taught us how sensitive laser engraving can be, and how crucial it is to test and adjust parameters before finalizing the cut.
For the 3D printing project, T-Rex model. The main challenge here was time management, we had to make sure the print would complete within a limited timeframe. To solve this, we asked our instructors for advice and discussed as a group how to optimize the print. We decided to resize the model and use a low infill quality, which significantly reduced the printing time while still maintaining the basic structure.

This week, I learned how to work with the laser cutting machine and the 3D printer.
These skills will be very useful in my final project. I can use laser cutting to create precise parts from materials like wood for the structure or decoration. The 3D printer will allow me to design and fabricate custom components that may not be available ready-made, helping me bring more creativity and functionality to the project.
Mercedes Key Chain (3D Printing)
Phone Stand (Laser Cutting)
The coolest thing I learned this week was how to operate the laser cutter and 3D printer all by myself. Being able to work on these machines independently gave me a real sense of confidence and accomplishment. I used the laser cutter to make a practical and creative phone holder, and the 3D printer to create a Mercedes keychain that reflects a personal dream.
Something I’ll never forget from this week is the moment I saw both final pieces come to life — especially the Mercedes keychain 😁
Also, the activity we did during the sessions 😂 was so cool and surprising to me, it made the whole learning experience more fun, engaging and unforgettable 😌
