Week 2 - Journal

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)

As someone who has worn glasses since I was 6, I’ve often thought about making them cooler.

Recently, I was inspired by geometric eyewear, which I imagined wearing at fun hangouts with friends—but I couldn’t find a pair.

So, I decided to create my own for this assignment. This is just the beginning because, honestly, glasses don’t have to be boring!

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

For the Laser Cutting (for the front face):

Fusion 360

RdWorks

El Malky ML149 Laser Cutter

Plywood

For 3D Printing ( glasses arms ) :

Fusion 360

Cura for Slicing

PLA Filament

Prusa MK3 3D Printer

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?

2D design for the front face of the glasses :

I started with drawing the circle ( first lens ) with a diameter of 48mm measurements taken from my eyeglasses.
Then the square (2nd lens) with dimensions of 48 mm height and 50mm width "inner part". For the outer rectangle 52mm width.
for the bridge its length is 19mm with a spline to give it comfy look
the 2 holes for the arms and screws , i made a square with dimensions of 5mm width & 5mm height. Inserted a circle with a diameter of 3.5mm.
Design is fully defined , for the bridge I used fixed as it was an spline

3D design for the arms of the glasses :

I started with drawing and setting the dimensions for the arms. The arm length is 120mm and the arc is between 26mm and 20mm which will give us total length of around 146 around the same measurement of my eyeglasses which is 145mm
Then I extruded both arms with 5mm
New sketch , added a rectangle of 10mm width and 10mm height. Extruded both with 10mm
New sketch for the holes , circle of 3.5mm diameter. Then extruded cut with -5mm to get a hole shape where the screws will go
I used chamfer and fillet to make the arms better looking

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?

For the 3D printing (arms)

Before exporting to g.code , i checked the parameters with the lab specialist all was good. We made sure temp is 215 and the design didn't need any support or adhesion of any kind
It took 10g and 40 mins
Parameters :

infill : 10%

pattern : grid

scale : 100%

For the Laser Cutting ( front face )

First i imported the dxf file to Rdworks to start the the cutting process after checking all parameters
The initial design had a very small / thin frame
I asked if I could adjust the sizes and re-make it. So I increased the space between the outer frame and the lenses on Rdworks and the final result was better than the initial one
Parameters :

Black for cutting

speed 100

power 30

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

Yes , I had some trouble with fully defining the front face of the glasses. I asked on our group and Menna (thanks to her ) she told me to check points not necessarily lines. I know it was mentioned in sessions 😅 but sometimes you need a reminder

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

I got stuck a lot to fully define the front face , I kept re-doing the design more than 3 times to get it right. The problem was that even when full defined when I exported it to dxf then import to Rdworks or LaserCad the design gets messed up. That was because the outer frame should be connected all together. So I drew lines and trimmed until I reached the result above which was the design I wanted and it was the same on Rdworks as well.

Trial and error is key , just make the decision not to get off the laptop until its done and voila it will be done inshaallah!

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

Designing both 2D sketch and 3D will definitely help in the final project, as I have to design everything in it. Trying early and making mistakes early is better than getting to do for the first time for the final project

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Designing on a CAD software like fusion 360 in itself was fun. I really enjoyed it

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
