Glasses holder
This review for a 3D printed file at Printables felt very relatable to me. I wear glasses myself since I was a pre-schooler. Up to this day, my husband still gives me remarks about my odd placement of my glasses. And I do spend too much time locating them multiple times a week.
So having a fun, cute designated place to put my glasses, will definitely help me not lose my glasses so often. It would also save my glasses from being stepped/sat on.
I made a realistic graph on canva
If I would make a graph representing the breakage reasons of all my previous glasses, majority would be by stepping/sitting on them.
UPDATE: After uploading the file in Ultimaker Cura, I noticed the project would exceed the printing time limitations. I am excited to make this project at another time. Below there is another glasses related project, but this time for safety glasses.

Hanging safety gear
Hanging safety gear
In the wood workshop we have to wear multiple kinds of protection gear to protect our ears, airways and eyes. The headphones and dust masks already have a designated place of storage. Yet our glasses are spread all over the workshop collecting dust. When we need to wear them, it takes too much time to find them.
Safety glasses on the hook
Safety glasses on the hook
This small custom hook design is easy to install on a wooden wall with a simple screw. It can be printed in different colors to differentiate between the glasses of each person. Or I can make a small backdrop maybe with personalized symbols or names.

These personalized tags can be easily installed behind the 3D printed safety glasses hooks. Adding a symbol or a name helps differentiate between the glasses of each team member in the workshop.

Which software/machines/materials did you use in the assignment? Why?
3D printing project
Part 1 of the assignment : 3D Print a model of your choice
Software:
Ultimaker Cura is an open-source software. The software can run on different operating systems. I downloaded the version for Windows.
Design:
On Thingiverse I was able to browse many designs. Initially I was interested in a slightly more complex design to store my glasses. The printing time exceeded the assignment's technical requirements though. I easily found a more suitable and still similar design.
Machine:
The Prusa i3 MK2 is a popular 3D printer which has a lot of positive reviews.
Material:
For this project, I will use PLA filament.
Laser cut project
Part 2 of the assignment : Laser cut a model of your choice
Software:
RDworks is a popular software used for laser engraving. It is suitable for Windows only.
Design:
I downloaded 2 shapes from 3axis.co. In RD works I made a frame around them personalized the frames by writing a name and initials.
Machine:
The El Malky ML149 CO2 Laser Cutter, a locally made laser machine.
Material:
For this project, I will use 3 mm plywood.

I drew 2 rectangles that can fit the size of the 3D printed glasses holder in RDworks.
I browsed on 3qxis.co to find suitable dxf files with nice images and downloaded them. After importing the files, I locked their dimensions and scaled them to the size I needed to fit the rectangle shape. I then adjusted the parameters for speed and power to give the desired visual outcome after producing. I saved the file in the .rld extension to be ready for the laser machine.
On Thingiverse, I found a suitable stl file of the glasses holder.
I imported the file in Cura and locked the dimensions.
On the feedback page on Thingiverse I read that some people found the measurements to be wrong while printing. So I double checked the dimensions before slicing.
I tried placing the back of the model on the bed to result in a shorter printing time. The time was indeed shorter, but more support and material was needed. So I decided to return to the original position to have a better finishing and use less material.
After slicing, I saved the file using its own parameters and settings in the description (36min_PLA_white_5g_0.2mm).

Laser cut project
I transferred the file via usb to the computer to upload it to the laser machine. Once I double checked all is in place I downloaded the file to the machine.
I moved the machine nozzle to the corner of the plywood sheet and decided on the origin. I pressed on frame and also made sure the lens was at the correct distance.
Once all was in place I pressed start.
In post processing the plywood needed minimal sanding for the burn marks.
3D printing project
After checking the desired temperature of the PLA with the maker specialist, I adjusted the file to 215 degrees. I transferred the file from the computer to the memory card to be inserted in the prusa 3D printer.
I selected the file with the turning knob and pressed to select. Then I selected start printing and waited for the first layers to be printed.
In post processing, I only had to remove a small support. Instructor Eman showed me how to clear the small hole with a stick shaped tool.

The first 3D print failed on the Prusa i3 MK2.
In the first layers the machine was lifting some of the brim. I asked for help from instructor Eman. She paused the operation and removed some of the lifted hardened brim.
I think the end print failed because of 3 possible reasons
1- I removed a small support I thought to be not vital.
2- The machine moved too fast, not allowing the layers to cool down enough.
3- Machine settings were maybe wrong?
The second print was successful after adding a support and making it on another 3D printer.

3D printed gear
The laser cutting will be vital to manufacture a box to house my prototype. I think that the 3mm plywood will be suitable and give the stretching box a nice overall look.
I am not sure yet in which parts I will use the 3D printer. Maybe for some of the turning gears in the box to rotate the illustrations.
WOW!

Anti-virus software is your best friend.
I had a small scare when there was a virus detected on a usb that went into multiple laptops in our group. In the past I always would ask my brother what to do.
Technical coordinator, Abdelrahman, explained how to solve this issue and shared the anti virus software with us. I felt empowered for a moment trying to solve this issue with his help, instead of fully depending on others to solve these kinds of problems.
Trojan infected laptop, not for long though!
