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)

wacom tablet

our assignment this week was to design a pen\pencil holder using fusion 360 and to print it using the 3D printer.

i have a wacom tablet and found on thingiverse several designs to a pen holder specified to hold the stylus adding effects or cartoon characters and i found a design that has a minion holding the pen.

the minion design i referenced

Tool Chain

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

the software used to interpret the designs to the machines were ultimaker cura and fusion 360

pla filament

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 found a YouTube tutorial on how to design minions in 3D and followed it to implement it in my design :

https://www.youtube.com/watch?v=QOb1s6K_zUs&t=3153s

in the design i used a combination of fueaters such as revolve , sweep, extrusion, emboss, draft and fillet.

my design consists of two components , the first one is the minion

i created a sketch of a half capsule for the body and revolved it , then created a circle sketch and sweeped it it along a path to create the arms , embossed the mouth sketch on the body to hollow the mouth, and created to cylinders to create the googles and hollowed them to create the eyes

and for the feet two cylinders were created to make the legs and cuboids for the shoes ,then i filleted the shoes to make them more curvy

the design after extrusion and joining into one component

the second part is the base , which is a simple disc that has two small tabs to secure the minion on it , and hole to secure the nip of the stylus

the two components after coloring

i hollowed the minions feet to secure them on the tabs of the base and hollowed the base to add additional weights after production to secure the holder

the two components joined

final design

i exported the components to stl. files and sliced each component alone to cut down the time

the minion part was moved to the side of the bed and rotated 90 degrees to the left and the following settings were made :

layer height was set to 0.2
infill 10%
done with supports set to (touching build plate only)
adhesion set to brim

time estimate was 58 min.

the base part was moved to side and rotated 90 degrees to the left and the following settings were made:

layer height set to 0.3
infill10%
done with supports set to touching build plate only (for the hollow inside)
no adhesion

time estimate was 34 min.

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 entered the files on the memory card and changed the filament for the minion to white then started the print

20220201_141151_1.mp4

the print was going fine but failed before the last ten layers

as the print was moved from place and the printer continued to print in midair.

final print with supports

20220201_144347_1.mp4

as for the base part , the filament color was changed to black before printing

the print went fine despite having some slight deformities that required post production

final prints

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 hesitated on how to print the minion in the best orientation possible, but i found help at the open time support session and the instructor Ahmed Khaled advised me to rotate the minion horizontally but said that any position will work fine with it

and Micheal Henry gave some good advises on how to do the post production in the best way possible .

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?

as the print failed before the final layers, i was left with an open print of the minion and didn't how to continue or repeat the print.

but the instructor amani ayman helped me and told me how to print the remaining layers separately , in an effort to complete the print

the print next to the remaining part

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

i could use the skills learnt this week and implement them in designing the horse automata and its separate parts to insure the highest quality possible

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

the coolest thing i learned is fixing a print even after failing is possible thanks to amani ayman

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.
