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)

Started By searching for the Scope Logo

My idea was simply a some kind like sniper glasses which half of it is a logo scope and other half is black glasses or eye cover

inspired by the challenge to design creative-looking glasses. I imagined a unique concept: one side styled like a closed eye, inspired by Nick Fury, and the other as a high-tech scope, similar to those seen in sci-fi movies or worn by characters like Deadshot.

Taking ideas of black glasses Styles for the design

After settling on the idea, I decided to split the design into two halves: one side would be a sleek, black eyeglass style, while the other would feature a sci-fi-inspired scope

Tool Chain

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

Paint as Draft

I used paint as draft to note my measurements and hand-sketch my drawing to make it easier to make the model

Fusion 360

I used Fusion 360 to model my design and to and make it at the final shape for exportation

Laser Works

after I exported the DXF files I used Laserwork to prepare the file for the laser cutting machine

Ultimaker Cura

after exporting STL files from fusion I used Ultimaker Cura to prepare files for 3D Printing making the slicing for the file

El Malky ML96 CO2 Laser Cutter

After preparing files as RLD extension I used the Laser Cutter to cut the sheets into the desired shape

Creality Ender 3 v2

I used the 3D printer for making arms of the glasses

3mm wood sheets

The materials used to generate the glasses face

Pla filament white

PLA is way too suitable for 3D printer and settings used for making arms model

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?

I took measurements from my own glasses

I wrote down measurements that I took

I started with grafting the main circles

Then I used spline to make a curvature-detailed glasses

With adding dimensions to the sketch to constrain it

By adding all dimensions and defining all the spline points we made the sketch fully defined

By giving the shape a thickness to make it closer to desired design

After that I give the shape appearance of the of the cut graft sheet

After sketching the arm I make the sketch fully defined

Then I extrude the arm sketch

I draft on the start of the arm to make the arm hinge

After extruding the sketch I draft circle to make a whole later

I extrude cut the circle I drafted

Then I move to fillet the arm

After the arm fillet it needs to get a good joint finish

I joined the arm with the face to Project then I use projections to make a good cut

I cut the excess areas that was projected

After cutting the shape for a good finish look we continue enhancing other sides finishes

I moved to the next step with joining screws and nuts

I make a joint between the screw and the hole circles I made in the face and the arm

Then I join the nut to the joint

I make the same in the Other Side by using the screw joint

Then doing the same with the nut

To take the outer dxf I need to empty the shape for the laser cut projection

After I empty the shape I use the laser cut extension to get my dxf projection

I choose a kerf with 0.1 mm because of the radius of the laser Ray

Then I move to the mesh step and export the arms as STL for the printing

After exporting our Design as DXF we head to Laser Work to prepare it for fabrication

At first we import our DXF file to Laser work

We orient it to the edges to the origin

I give colours too areas I want to cut , scan & Speed cut

I change parameter for black colour to sit at 80 Watt for cutting as lower than that cause the sheet not to be cut well

I set speed for black colour as 20

I set speed for red colour which is for scanning as 200

I set it's power as 65 as I want it Dark graving

I said it's value for can to make sure that it is for graving

For the blue colour I set it for Speed cut

I also set its power as 65

Now with all set I head to the file saving

If I want to see the results I click on simulation preview

By following the simulation to the end I see how the machine is going to cut the sheet

Then after connecting my laptop to the laser cutter machine I download the file on the machine by clicking on download

Now after all is ready and set for cutting I can head to fabrication process on the sheet

For the arms of the glasses, after exporting them as mesh STL format we head to Ultimaker Cura to slice them prepare them for 3D printing

In Ultimaker Cura we open our files to slice

We import files in STL format to slice

After importing we adjust the orientation and files position printing

We use the feature of move and port to adjust their location and orientation

We adjust both arms location and angle

After adjusting the suitable position we click on slice

For me as I as I wanted the less time I could get I change it the standard settings to the low quality settings

As an advice I took the two millimeter thickness of the arm would have no issue with 0 % filament

After sitting all the settings I head to preview

I check layers preview and get my slice result as 36 minutes

Finally I head to the file saving to save it LG code then copying it on the memory card and head for printing

Now after file is on Gcode format and we load it on memory card we head to printer to plug the card and start printing

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 Laser Cutting

I connect Laptop to the machine via usb cable

I click on "download" on laser work after connecting laptop to machine

I click on Udisk+ using buttons

I copy my file to the machine memory by clicking "copy to mem"

I click on file button and click on my file using arrow buttons

Last i click "Run" and close the lid and watch my job getting done. like taken videos and photos below

Here my job finally getting fabricated by laser beam cutting 3mm wood sheets
to product the wooden front cut of the modeled glasses

After machine finishes scanning it proceeds the process of speed cut and after that the process of separating cut

After giving face some appearance

Final Shape of face

Shape of Glasses after Laser cut

For 3D Printer

I attach the memory card to the machine carrying the Gcode file

By rotating and clicking the main button i choose print when this screen appear

I choose my file from files screen by the main switching button

Then I follow and watch my job getting done and printed and in anticipation if thing happens

Watching the arm being printing by adding additional adhesion layer to the ground to avoid the last time printing mistake (The arm was unsticked during the print)

Copy of VID_20250807_210343_349.mp4

Copy of VID_20250807_210416_644.mp4

After a period of time we see that arm is half completed and supports start to show up

The arm is nearly done and adhesion and support are stuck to the arm to give the arm additional strength to avoid falses

Copy of VID_20250807_210443_016.mp4

Copy of VID_20250731_185918.mp4

After facing some problems on printing the 2 Arms were successfully printed Left one unsticked During printing so it was reprinted individually

And now we remove supports and adhesion layer and excess parts to get the part in its final shape and a good finish

And here comes the final shape of arms after printed

During excess areas removal

And here comes the final shape of Glasses

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 asked Ahmed FabLab specialist for fastest settings I could set for getting printed results .I got very good time which was nearly 13 minutes for each arm after it was 50 minutes both.
also I asked Ahmed FabLab specialist for the most suitable power for machine to cut as it didn't cut at 65 watt, and I got the answer for making it 80 watt which was suitable .
I asked on How I could make dark grave as I wanted to make the grave in glasses more darker than usual and i wanted the suitable value without risking the file to burn , I got help form Ahmed FabLab specialist and I sat the value as 65 instead of 30 .

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?

First wooden sheet couldn't get cut and the job made was still in the sheet , without being able to come out.

The technical solution was to set power as 80 as 75 and 65 were not enough for cutting
This was the advice Ahmed gave me when I was stuck and needed solution

Second Left arm separated from the bed while being printed and its print missed up

The technical solution was to add adhesion to make a thin part like arm maintain on printing bed till end
But before trying this solution me and Ahmed tried to fix the print by tape on its position many times as it was only few minutes for the print to finish but after these trails it didn't work and solution was adhesion layer on print settings

Final Project

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

I learned how to use M3 screws to connect wooden parts with 3D-printed parts, and how to model the screw holes in both the wood and the print.

I found out that the adhesion layer reduces the final surface finish quality but also increases the bond strength between the print and the bed — so the choice depends on the print’s purpose and the desired finish quality.

I learned that 65 watts produces a very dark engraving.

- - I discovered that when designing screw holes for 3D printing, it’s important to slightly oversize them to compensate for shrinkage after cooling — for example, drawing a 3.3 mm hole if the final needed diameter is 3 mm.

All of this can be considerd in 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?

The coolest thing this week was an extra session where we made origami and talked about documentation. It was a really fun and cool session , we folded an origami frog out of paper, and I also made an extra rocket.

It was a really really realllly enjoyable & funny session I really had fun in

Origami

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.

In the hands-on session, we were tasked with making a reading bookmark shaped like a robot , with its head 3D-printed and its body laser-cut. We built it successfully, with the condition that the head could be attached to the body using M3 screws, and we made it work.
The whole robot was designed using fusion360 . Head was modeled then saved as STL mesh . and Body was 2D Sketched then exported as DXF.
