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)
This week's assignment is to design and implement a simple mobile holder using the features we learned in Fusion 360 software, as well as using a screw and nuts, and it should be made of at least two parts and suitable for flat surfaces.
The "hands on minds on" activity helped us in search and inspiration from the beginning. I found a model based on the 30,60-degree triangle and started working on it and producing a prototype using cardboard.
my idea is simply that the mobile holder is able to carry the mobile at two different angles, also can carry two mobiles at the same time, while containing a storage space inside it suitable for placing a charger or a small power bank, as well as containing slots for entering the charger wires and openings for ventilation and decoration.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Software:
1. Fusion 360, to design from scratch on sketches and saving it as a DXF file to develop it on Laser work software.
2. Laser Work, to develop and set up the settings for laser cut machine.
Machine: MT3050D CO2 Laser Cut Machine.
Tools:
Screwdriver to join the screws and nuts.
Sandpaper to smooth the surface and remove the effect of the laser beam.
Material:
Plywood 3mm, it's suitable material for this design.
screw and nuts, to join sides and bottom parts.
Clear spray for the finish.
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?
To design the mobile holder, I started by preparing a prototype using the cardboard to calculate the dimensions and measure the connections closer to what will be implemented, then using the ruler I read the measurements, transferred them to the Fusion 360, and started drawing sketches on different surfaces for assembly later. After completing the drawing of all the parts, I assembled the shape to ensure the dimensions of the connections, then I extracted the DXF files for each part and prepared them on a laser work program, and I imported an Islamic geometric shape from the design of bookmark that I made it before, to make the ventilation holes and I set them in the right places and I adjusted the cutting settings And save the file as RLD to work on the machine.
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?

First, I copied the RLD file to a flash USB to copy it to a laser machine computer.
I checked the file with the specialist, after that, I downloaded the file to the laser machine.
I chose the material, which is plywood with 3 mm thickness, and put it on the working surface.
I adjusted the focus, the origin point, and the track frame.. checked the settings, and then ran the file.
Within seven minutes, the result came out, but after implementation, we found that I missed a tiny line, so I went back to the original file to draw it with new color with the same cutting set and repeated the process again but I made the output of the previous cut setting is no to ignore it when I ran it on the second time.
after finishing, I finally got my mobile holder and made some post-processing like sanding, then I assembled the bottom and the sides using screws and nuts and then assembled the rest of the parts by pressing and finishing the product with clear acrylic spray.
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?
Anas and Nada helped me understand how to save files on Fusion.
And I am very grateful to Ahmed Abd-Elnaser that he allowed me to attend Saturday lecture via Google Meet, and the challenge was to continue working with them and join Ahmed Hussein in a group work to design the chair, and we designed the chair completely. But a problem arose when I exported it to the Laser Work and Amani helped me in the support meeting.
The problem was that an extra line appeared and did not appear in the Fusion file. It turned out that this error is common, especially when using curves or the Spline command, and the solution was to check all sides of the shape to re-adjust the curves through Laser work, then separate the line, erase it, and redraw the space once other.
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?
Assembling the shape with this inclination was not easy, and I drew some parts in the wrong sketch and repeated again on the right one, I experimented many times until I got to the right shape, and making the shape fully defined I understood it too late and I replaced that with the fix command.
One of the problems that appeared after implementation was the problem of wood curvature, which led to the piece being unstable, but this did not affect the function of the piece significantly, so it still works efficiently. It is possible to remedy this by increasing the width of the long top side and installing it using screws and nuts, and the entrance to the storage unit is the short surface only. And another problem is the narrowness of the space for the charger outlets, and the remedy for this is by canceling those entrances from both sides of the piece and sufficing with a lower slot at the stand with a reassessment of distances.
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
A large part of the final project will be based on the interlocks and connections of geometric shapes, so this week’s task helped me to train on this type of drawing and how to prepare and apply it to the Fusion 360 and to experience this in practice, and I found several points that must be taken into consideration such as lines Overlapping and the importance of removing them using the Laser Work before downloading the file to the machine, in addition to the importance of verifying the completeness of the shaps, whether on the program or after implementation.
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
This was my first time designing a shape with connections and assembling it through 3D design software, it always felt difficult, but once I started following the instructions and making the first design it became possible and easy and I will keep practicing.
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.
The design of a a Miniature Rocking Chair was one of the best design experiments that I trained on this week and I enjoyed a lot while working on it and experimenting working with curves, and after implementation it became my favorite piece and always in front of me at my desk.
