The assignment this week is a 3D printed pen/pencil holder
The reason I care about this idea is not because it is mandatory, nor because it is this week's assignment, but because of course I had a punch of pens and pencils in my working space, and for more usage of every possible space available as well as giving a glimpse of order in my working space, I decided to do this pencil holder.

Which software/machines/materials did you use in the assignment? Why?
Autodesk Fusion 360
Used to transform ideas and low-fidelity prototypes into can-be extruded sketches, with format STL files.
Ultimaker Cura
Used to transform the STL files into a g-code compatible 3D Printing files.

Autodesk Fusion 360
Input.
- Ideas: Inspired from surfing the internet.
- Measurements: Inspired from a low-fidelity prototype.Expected Output.
- A STL file.The process in the middle.
- Created our first sketch.
- Chose the plane to work in., then built a 3D shape: Cylinder.
- Applied shell modification to the cylinder to empty the core of our pencil holder.
- Then created a center to center slot, then applied the emboss effect using the slot on the walls of our shelled cylinder.
- Applied circular pattern of the embossed slot around the shelled cylinder.
- Added bronze patina material to the body to give an appropriate appearance.
- Final step was applying filled to all the edges of the pencil holder.
- When checked that all dimensions and constraints are fine, saved the body as STL file.

Ulrimaker Cura
Input.
- Receive STL file produced from Fusion 360.Expected Output.
- A ready to be printed by 3D Printer G-Code file.The process in the middle.
- Check that the project is set to the right printer and right printing material.
- Drag the STL File to the program.
- After importing you check and set the scale.
- Then you lay the model on the best position that will need the least external support possible.
- Make sure that the model is laid on bed in the same position we chose.
- Change the position so that our model is not centered above the two center screws.
- Then set the model printing parameters:
(1) Profiles: 0.2 mm.
(2) Infill: 10%.
(3) Support: None.
(4) Adhesion: None.
- Then we save to disk, so that we have our final g-code File.
3D Printer
Turn on the printer and then insert the SD card.
Start printer Preheat through printer's controls.
After preheating is done, we chose Unload Filament from the printer's controls.
Then we remove the filament.
Choose Load Filament from the printer's controls.
And be in this phase until the color of the new filament appears to be able to proceed from this step.
Then we clean the bed before start running the printer.
Then choose the file we want to run from the SD card and press run.
We monitor the first couple of layers so that we can contain any faults of the run in the beginning.
Let the printer finish and then we extract the model from the printer bed.
Wait until the printer temperature goes down.
Turn off the printer.
After finishing the 3D printing process, the pen holder had a quick smoothing, and was tested right away if it can hold pens and other lab items and stand still while holding them, and it succeeded.

After finishing the 3D printing process, there was a few hairs sticking out of the object as well as a piece of filament that wasn't properly heated, so I approached the fab lab specialist and asked him about how to solve this, and he showed me how to polish the outer layers of the object using a piece of rough polisher tissue that is used for this process.
Overcoming Challenges
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?

While performing the 3D printing process, I encountered a problem and that the first layer was not properly printed and so on the printing process was going to failure, accompanied with the fab lab specialist assistance, we stopped the process so I could be able to check where things gone off, and It was related to printing above the two pins in the middle of the printer.
Changed the model starting point and made sure that the right face are correctly laying in the printer's bed before re-running it again, and it was success :D
