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)

My beloved Stitch

This week we were supposed to make a pen and pencil holder to enhance our designing skills while using Fusion 360.

My inspiration for this week is one of my favorite cartoons characters; "Stitch"!

I love this cartoon so much, so I decided that my pen holder will take its head shape.

Tool Chain

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

From its name, "Fusion" has many features that makes it the right choice for software designing tool.

This week I used Fusion for 3D model designing as I did on the last week. In addition to that, I used 'Cura' to adjust the settings of the file and change the extension of it to be'.gcode'

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?

The final look

Using 'Centre Circle' option from the 'create' section to form a circle

Then using 'Line' option to form a line in the upper part of the circle and the same in the lower part, then a line to join between those 2 lines vertically, after that' using 'trim' option, I deleted the rest of the circle until this shape in the image remained

In another sketch, I drew the ears using 'Fit Point Spline' option in 'create' section

Clicking 'Finish Sketch', then going to slid mode in order to choose 'revolve' option

We will choose 'revolve' option for the half semi circled shape and 'Extrude' for the ears in order to give it a dimension

In Extruding the ears, the operation will be 'join', then in order to hole the figure I have used also 'Extrude' but with 'Cut' operation..

In the x-y plane, I drew a circle with a diameter smaller than that of the circle drawn in the first step

Then using the 'offset' option in the 'construct' section, I will make another plane parallel to the x-y plane and above it

I will chose 'design' in 'General'

Then I will 'Allow 3D Sketching of Lines and Splines, click 'apply ' and finally I will click 'ok'

Drew a circle of the same diameter as that in step 8 (on x-y plane) then clicked 'finish sketch' and used 'Line' option to draw lines to connect the 2 circles

Finally I used 'loft' option in 'create' section in the 'solid' mode

And last but not least, I used 'extrude' with 'join' operation.

Adjusting the settings of printing on 'Cura'

Slicing the figure in 'Cura'

After slicing, it will take 52 min and consume 6 g of plastic

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?

The final output, with broken ears 🤦🏻‍♀️

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?

After finishing the printing of the design I had 2 advices, the first was to increase the thickness of the design to decrease the possibility that a part of it will break like what happened with my design this time.

And due to the low thickness of the design it couldn't stand steel when once anything is put inside it, so Saeed advised me to use a double face tape to fix it on the desk so it won't fall.

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?

Yes, I have faced some problems in the loft feature, so I returned back to the its tutorial to recap the steps I forgot about them while am working on the holder design.
