Tool Chain

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

Machines :

Materials : 

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?

Design :

1- Starting with rule number 1 to create a new component named Base side.
2- I started sketching with the base side to be a guide for me in sketching the other 2 angled sides so I started with a 2mm x 80mm rectangle on the top plane with 4 circles in 3mm diameter for the brackets.
3- Drag the bracket with captive nut to my file and checked its dimensions to be 3mm length with 60 deg angle and.
4- Make 3 copies of the bracket to get two for each side.
5- Join the brackets with the hole in the base side.
Note: The tabs in the base are added to the sketch after sketching the front and the back sides. 

6- Create a new component named Front side.
7- Start sketching on the bracket face to project the 3mm holes on the front sketch and save the angle of inclination.
8- Drawing the holes of the pens by arraying a 10mm diameter circle for 4 copies in the X axe and 3 copies in the Y axe with 5mm                    distance in between.
9- Make sure that the hole didn’t intersect with the bracket and make 2 wider holes for markers far enough from the bracket too.
10- Make a slot for the mobile with 80mm width and 15mm away from the base side.
11- Making the paper notes slots by arraying a 2mm x 50mm rectangle for 6 times with 3mm distance in between with an enough space from the bracket too.
12- Extrude the front sketch with 3mm.
13- start to make tabs and slots between the Base side and the Front side to stick together well. 

14- Create a new component names Back side.
15- Start sketching on the bracket face to project the 3mm holes on the front sketch and save the angle of inclination.
16- Making slots for the paper notes with the same dimensions of the front to be aligned well after assembly.
17- Making the mobile aligned to the one on the front side but with editing the dimensions to work as a stand for the mobile so sketch a         rectangle with 80 mm width and 65 mm height. 
18- Make tabs and slots between the front side and back side in the remaining distance after cutting the mobile slot to be fixed well.
19- Realizing that I need a bracket between front and back side on the top with taps and slots to be fixed well so I edit back and front sketches to open 3 mm holes for the bracket.
20- Extrude the back sketch with 3mm.
21- Join a bracket to the back side. 

The Final Assembled Design 

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?

2- Import the DXF files into RDWorks and nesting them.
3- Set up the parameters as fellow :
    Speed (30) Power (50). 

3d printing preparations :  

1- Export the bracket into STL file by right click on  the body of the bracket and select save as mesh and select (STL binary) in high refinement.
2- Import the STL file to Cura and lay flat to the bed and choose the multiply part option to create 4 other copies of the bracket and arrange them then slicing with the parameters as fellow :
                                                                                                     - Layer height (.3) ( extra fast).
                                                                                                      - Infill (10%).  
                                                                                                      - Support (None).
                                                                                                      - Build plate adhesion (Prim).
                                                                                                      - Nozzle temp (215) Bed temp (60).

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)

It was a challenge for me to make a suitable dimensions for every component in the design from the first time  and to fit everything easily without missing thing in the design or having to refabricate any part. 

It was somewhat difficult to get the screws in place in the brackets so I had to sanding the brackets holes a little before connecting the screws. 

Final Project

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

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.
