Week 3 - Journal
Pentagon Pen Pot Holder
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)
Title of Media
I like polygon shapes specially pentagon , so I searched about pen holder with polygon form , and modify it with pentagon open on other sides
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
MK2 3D Printer
material: PLA
Software: Ultimaker Cura
Title of Media

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 draw pentagon on Autodesk Fusion 360 with 55 mm diameter, then extrude it with 52 mm height , press shell on top of it with 3 mm thickness , draw random pentagon on it's sides and extrude it with cut to make open on the surface with pentagon shapes , give it matt yellow colour and plastic material ,after I finish the form , I save it as .stl to prepare it for 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?
I open the .stl file on Ultimaker Cura program
I choose the printer Pursa i3 mk2 , the material PLA , the resolution 0.2 , the infill 20% .
After I finish the setting modifications, I found the printer will take 2 hours , 23 minutes which is very long time , we should make it in 90 minutes not more that , so I saw some videos on you tube to help me how to reduce the time , the links of it :

so after I watched that videos I reduce Infill to 10% , I make the print speed 60 , infill speed 60 , so the time became 1 hour 19 minutes , after i finish i named the file with : PI3MK2_3dpenholder_1.19h_pla_blue_20g_0.2mm.gcode
Title of Media
After printing , I used the tools to cut the supports
Overcoming Challenges
What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)
I didn't put any support in the file , so the instructors Mohamed , Basant in the lap advised me to put support the form , so the time increased again , so they advice me to make the support overhang angle to be 55 , support density 7% , support z distance to be .2 to make it easy for me to remove it , so the time of printing became 1 hour , 33 minutes
Title of Media
after i finished my product i have some scratches on it , so Mohamed advice me to use heat fire on it , and it fixed it

Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
Title of Media
I think getting familiar with 3d printing machine and ultimaker cura program , practice more with Autodesk Fusion 360 program , all of this steps will help me 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?
