Week 3 assignment was to design and fabricate a pen and pencil holder. I choose a practical design to contain the large amount of pen and paper I have at home.
Output:
1) Pen andPencil Holder
Source of Inspiration:
Find my reference in this link, and see it in the image as well.
Reference Design
Software:
1) RD Works V8 | For Laser Cutting
2) Fusion 360 | For 2d and 3d Design
Machines:
1) Laser Cutter
Model (El Malky ML149 CO2 Laser Cutter)
Materials:
1) Plywood (Laser Cutting)
The answer to The "Why" is because this is these machines and materials are what is available for us so far in the Maker Diploma scope.
Sketching and Dimensions
I started doing freehand sketches and choosing my own dimensions.
I did the design myself on Fusion 360 software.
I made all the sketches fully defined.
Fusion 360
Design
I fully defined all scetches.
Named compomments Correctly
Made my helder contain multiple compartments closed by 4 faces.
Multiple Compartments
opened the file on the FabLab computer to ensure all parameters were correctly set.
Powered on the machine.
Adjusted the nozzle's focus and tested it using the pulse button.
Set the origin point for cutting using the origin button.
Transferred the files from the computer to the machine.
Started the machine to initiate the cutting process.
Ready for Cutting
After Cutting
After this I moved to assembly part to link all pen holder sides and joint the T-Slot parts with M3 screws and nuts.
Title of Media
My instructor advised me to make the middle face that is separated in the image with tabs instead of making it into 2 parts.
This saved me time and effort because the shape was starting to get a bit confusing because of multiple elements.
Too Many Faces to Join
Jointing all these faces in the app was challenging and not easy.
I had to utilize show and hide for faces.
2) Middle Face Assembly
I had to design the middle face that separated compartments at the end.
So I had to re-edit the scetches and repeat extrusion
I faced some issues like "body duplication".
The instructor helped me to overcome the challeges.
3) Speed Cut Mistake
By mistake in my first attempt I made all engravings speed cut instead of cut.
This happened because the layer of speed cut was named "cut" and I didn't check speed and power.
Instead of wasting the wood sheet I put it on the other side and cut it correctly.
It left the speed cut engraving to remind me to always check parameters.
Title of Media
I learned how to make multiple faces design with too many sides.
This will help me in my final project.
