Week 2
Minnie Mouse Sunglasses
Ideation
Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)
This week’s assignment was to design mixed-design glasses; the front frame was to be fabricated using a Laser Cutter & the side arms were to be fabricated using a 3D Printer, then to attach them all with screws and nuts.
Searching Google, this picture inspired me to do my glasses just like it as I love cartoon characters and Minnie-mouse is one of my best.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Fusion 360 software to design extrude, assemble all parts, and export .dxf & .stl files.
Ultimaker Cura 5.2.1 software to slice the .stl model and create the .gcode file for the 3D printer
LaserWork V6 software for nesting objects, setting the suitable parameters & creating .rld file which compatible with laser cutting machine
Prusa I3 MK2 printer to read the .gcode file & print the 3D physical object
El Malky ML149 CO2 Laser Cutter to read .rld file then cut or engrave or speed cut the plywood sheet
Plywood sheet 3mm to fabricate the front face
PLA+ for the side arms
Screws and nuts for the assembly
Design/Preparation Process
Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?
- The Side Arms
1- It was designed in two planes using fusion 360
A new sketch was created and the arm was designed by using lines and arcs and fully defined by dimensions and constraints
Another sketch was designed for the small part with a hole of 3.3*3.3 mm for the assembly
All dimensions were calibrated with my own sunglasses
Some features were used like fillet, extrude to 3mm, and extrude cut
A customizable appearance was chosen (PLA material & red color)
.stl file was exported
2- The .stl file was imported by Ultimaker Cura software, after choosing the printer ( PRUSA i3 MK2 ) & the material ( PLA)
The arm was laid flat on the large straight part; so no extra support is needed
It was multiplied to have another arm
Profile: 0.15 mm
Infill: 20%
Support: no support
The best orientation is chosen
Brim: None
Number of layers: 60, weight: 8 g, time: 58 min
.gcode file was saved
- The Front Frame
1- Design using fusion 360
A new sketch was created and only the right side of was designed by using many tools like circle, rectangular, arc, and spline; then defined using dimensions and constraints. The free spline shapes were locked
A hole of 3*3 mm was added for the assembly with the side arm
All dimensions were calibrated with my own sunglasses
Then, the right side was mirrored to have the complete design
It was extruded to 3mm and a suitable appearance was chosen
Finally, .dxf file was exported using "splines as polylines" extension
2- Preparation using LaserWork
.dxf file was imported
The cut area (black) was defined with a cut speed of 25 & power of 65
The (red) part was speed cut with a speed of 200 & power of 25
Finally, the file was saved in .rld format
Development/Implementation Process
Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?
The 3D printer was turned on and the SD card that contain my .gcode file was inserted into the machine
The printer was preheated to unload the old filament, then the new filament was loaded (the color of the new filament was checked to ensure successful loading)
The proper file was selected and run
for more details, click here!
- Firstly, the machine was turned on & the .rld or .ai file was imported
- The cut & speed cut parameters were checked, then the file was downloaded to the machine
- plywood sheet was inserted into the machine, the focus was checked using the focus block and the origin's position was adjusted by pressing the "origin" button
The proper file was selected, and the "TrachFrame" was run to check the used area, then we pressed "run". It spent 69 seconds.

Then, The front frame was colored ^^
Screws & nuts were used for the assembly of the arms & the front frame.
Overcoming Challenges
What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)
The definition of splines was very difficult, so I locked splines as mentioned in the self-practice videos & defined any other shapes
I duplicated the arm instead of mirroring it; however, it worked & I learned the lesson! (Solution: to mirror the arm, Areeg told me ^^)

Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
That's my first time to work with fusion 360 & design a 3D model, definitely, it will help me a lot on my final project!
WOW!
