Design a model of a pen and pencil holder that may rest on a flat surface (Table Top).
Description:
Design the model as a single 3D Object using Fusion 360 and fabricate it using 3D Printing. Be creative and come up with the coolest pen and pencil holder!
Technical Requirements:
The model is a result of using at least two 3D design features (Revolve, Sweep, and Loft) or the sub-features in Fusion 360. An "Extrude only" model will NOT be accepted.
The model is customized using the appearance features (Color, material...etc)
The model is exported in an *.STL format and file(s) is included.
The model is efficiently sliced (good orientation, minimal supports... etc.), 3D Printing parameter values are clearly defined, and doesn't exceed the time or weight limit (30 grams or up to 90 minutes).
The model is fabricated using 3D Printing and final outcome is demonstrated
Inspiration of pencil and pen holder from https://www.thingiverse.com/thing:5436449
Inspiration
I would like to do some parametric shapes and simple ones at the same time to avoid any faults while printing and stick to 90 minutes. so I decided to get inspired by this vase as it has a repetitive pattern on its body so I have analyzed the profiles he used and its scale.
Final simplified output of a pencil and pen holder
The final output after setting appearnce
The model is modified to not make waste of materials and tried to make it larger so I decreased the amount of details and get the best use of the materials in the size and scale of the shape so it can fit up to 5 pens printed in 90 minutes.

Which software/machines/materials did you use in the assignment? Why?
Which software/machines/materials did you use in the assignment? Why?
I used fusion to sketch the 3D design and export stl file that can be sliced for printing.
I used cura to slice the stl file , change settings and export G code file to be read by the 3D printing machine.
I used PRUSA to Fabricate my design.
I used PLA because it is one of the most environmentally-friendly 3D printing materials

Fusion 360 : Screenshot of the PROFILE 1.
Design Process using Fusion 360
First : I opened Fusion 360 to sketch my design .
1- Create new sketch .
2- I draw an inscriped polygon 8 sides and repeated an inverse one then i trimmed the inside sides.
3- I choose offset plate 20 mm distance between them .
4-
6- I connect them using Loft feature.
7- I use shell feature to make hole in my design.
8- I change the appearance using plastic translucent glossy white to make it looks beautiful .
9- Finally choose save as mesh choosing stl.
Note : I put all the process in the right . you can see it by click on it in the right side .
save to disk > g.code file (1hr30mins-14gm-Nariman)
Fusion 360 : Screenshot of the PROFILE 2 a square shape.
Second profile 2
I constructed a plan on z-axis for 30mm and 60mm height to draw profiles 2 and 3
Then I draw another square in a larger measurements to be the last profile (ending)
Fusion 360: Profile 3 in the middle made of 16 polygons and the largest in size
Profile 3 in the middle
1) profile 3 is the middle profile so I volumed it and scale it. It is created with 16 inscribed polygons.
Fusion 360 : Final output made with profiles> loft> appearance> shell
The Loft profiles and their arrangement
1) Final sketch I made loft and choose the three profiles in their arrangement.
2) Then I gave it an appearance of aluminum blue color from searched library
3) I have added a shell feature with a 3 mm thickness
ultimaker Cura
ultimaker Cura
1) I exported the file as .stl and saved it
2) I used cura to rescale it to fit 90 minutes
Development/Implementation Process
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?
Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?
Implementation
First : I opened ultimaker cura and open stl file to change the setting to be suitable for the requirement of the assignment :
Then I used :
1- 20% infill.
2- 0.2 layer height.
3- No adhesion or supports.
4- Temperature 215
Last step : I save the file as G-code ( writing the time , grams , material , color , infill and layer height) to be read by the machine.
The process :
1- I transfer my G-code to SD card and put it into the machine.
2- I cleaned 3D printer bed using alcohol.
3- I turned on the 3D printer.
4- I cut off the extra part of the PLA.
6-choose my G-code file.
7- After the bed become pre-heated i watch the first layer to make sure that all things works well.
Finally : It tooks 1h30m and 21 g.
The following figures shows the final output of the model :

1) I have asked Amany and rechecked the data inputs before transferring the files to the machines.
2) I watched this tutorial before i start and checked how to manage the profiles and manipulate them
https://www.youtube.com/watch?v=TH2XQ_3r48M
3) In the selection of profiles in loft the selection should be in ascending order from base to bottom it shouldn't be haphazard selection otherwise, an error that the mesh is not recognizable will appear.
4) I didn't do an offset but to the shape to avoid any waste of material but a shell of 1.5 mm was enough to give it its thickness.
I wish I could do this shape but I doubt it will be printed well as I have tried before to print a similar very high detailed shape and it needed a huge number of supports and it broke immediately so I have learnt to make it simple with enough connection. This is a very fruitful tutorial :D
Final Project
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
How can you use the skills and knowledge that you've acquired this week in your final project?
1) I have learnt how to design parts of the final project and print them in 3d.
2) I learnt how to make 3d Objects and commands such as sweep, revolve, loft and else which will be the main tool I will use in the final project design of the fixation parts and the applique covering.
3) I learnt how to make the connections and joints with subfeatures to print them with joints.
WOW!
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
We have learnt how to do a 3D livable 3D Printed and designed of our own. Also the subfeatures and sectional analysis to study how objects are integrated together and stacked with joints. Therefore, i have watched this GIF and it made me curious to make this model now i know how to do this example shown in the figure.
Example of how the joints are made in 3D printing and how we can make them dynamic
