Week 3 - 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 was to design a 3D pen holder, based on what we learned from the new features in Fusion 360.
I inspired the idea from the wooden arabesque shapes, I made only one sector to fit the time frame for implementation.
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Software:
1. Fusion 360, to design from scratch on sketches and making Extrude. Fillet, chamfer, shelling, and saving it as an STL file to develop it on Ultimaker Cura software.
2. Ultimaker Cura, to slice and set up the settings and generate the G-Code for the 3d printer machine.
Machine: PRUSA i3 MK2 3d printer Machine.
Tools:
Sanding paper to smooth the surface
Cutter to remove the support
Brush for coloring
Material:
PLA is a suitable material for this design, as well as easy to make post-process on it.
Brown Acrylic color 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 pen holder, I started by taking the measurements of the pen to know the appropriate diameter for it, then I took into consideration the thickness of the shape from the outside and I started drawing arabesque shapes starting from the bottom and building the sketches on top of each other after each extrude command, then I used a command shell to make the thickness and empty the shape from the inside and then Fillet, chamfer commands to smooth and refine the external shape to make it as close as possible to the real arabesque shape.
After completing the design and adding the appearance to it, I saved it as an STL extension to import it to Ultimaker Cura and then started making the settings for printing, this shape requires making layers for support. then I saved the file as 3MF file to check it before printing it with the Fab lab specialist.
Dimensions: 2*2*8.6 cm
Material: 18G - 6.18 PLA
Settings: Layer hight = 0.3 - Infill = 40%, with support
After all of this, I realized the error before printing and I will explain how to fix it...
Before the printing stage, I realized that the shape of this design will not bear the weight of the pen, no matter how much it contains support from the inside. The shape of the bottom must be larger so that it becomes more balanced and bears the weight on it.
so I went back to Fusion 360 and removed the chamfering step and made an Offset plan under The base of the shape, then I drew a square with a dimension of 3.5 cm, then I selected it and the square of the base, then I used the LOFT command and adjusted the shape as shown, then I extracted the STL file again to slice it on the Ultimaker Cura program, then generating G-Code to print it.
steps on time-line
After completing the LOFT command, I used the Fillet command to smooth the new edges.

Final Setting:
Dimensions: 3.5*3.5*9.4 cm
Material: 22G - 7.48 PLA
Settings: Layer Hight = 0.3 - Infill = 40%, with support
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 reviewed the 3MF file with Omar and I extracted the G-code "PrusaM_arabesque holder_22g_1hr30min_0.3q.gcode", I copied the file to SD Card for 3d printer.
I checked the bed and clean it, I put the SD Card, turned on the printer, choose preheat option then I wait for the nozzle until reached 215 degrees.
Then I started working on the file, I chose to print from the SD card, then I chose my file and the printer started working. After about 1hr.23 minutes it finished, I waited a few minutes and then pulled the piece off the bed gently and removed the support, then sanded it and coloring it with brown acrylic color.

Removing Support
While removing the external support, I was shocked by this fracture, and I treated it before the sanding stage using Super Glue.
I used sandpaper number 320 to smooth the surface a little bit and remove some appendages from the support layers
I used a brush and acrylic brown to color the surface and black to add a slight antique touch
Final Product
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?
I was having a problem saving the file with the STL extension correctly and I found the solution in Slack before I even asked
I tried to help Ahmed Abdel-Fattah by providing the solution that I reached by experience because I think it is suitable to solve his problem with his design
I helped Rawan to find a solution to the problem of breaking a delicate piece of the mobile holder, by suggesting to use Super Glue while keeping the piece in a tissue so that it does not break again.
Also, I helped Shorouk in adjusting the print settings for the pen holder project to fit the time frame for printing.
I also learned from the method of saving files to the printer, how to save my own files, especially the files of designs that I work with because it is a very organized and accurate method.
Anas teach me how to extract a video from Fusion 360 to make a motion video of the design. it was from animation tap.
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?
My teammates and I had a problem drawing this part of LEGO, we chose to use the LOFT command and it was a rather wrong decision because some of the measurements were not available, in addition to the fact that the interior space from the bottom is complex and contains many details.
Ahmed helped us at some point in which we made a mistake by drawing the upper part in the wrong plan, and through that, we learned about a projection command, and Nada helped us by providing us with some tutorials about the Loft so that we could later draw the piece in the right way using the Loft.
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
This week, we learned the connections and mechanisms of movement in Fusion 360, and this will help me in designing the final project, imagining its movement and making the necessary connections for that, as if it was necessary to make a 3d shape to make opposite movements, the training on the 3D printer will help me to implement this.
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
I learned from this design the mechanics of the movement and its connections, and I enjoyed working on it a lot.
Finally, after many attempts, I learned how to make the shape fully defined. Nada helped me to understand this point as well
I've learned to extract good quality images with Render, and I'm still figuring out that point
