Week 3 - Journal

Ideation

The assignment idea is to design and fabricate a pen and pencil holder.

I have already searched a lot about them but in the last assignment using wood to make a 2.5D object, not a 3D object.

My inspiration came from many websites like 3axis.co, thingiverse ,and yotube.

In the last assignment I used many T-slots so my inspiration came from the nuts I used

Tool Chain

I used Autodesk Fusion 360 to sketch the design of the 3D part.

After finishing the design, I used Ultimaker Cura 5.1.0 software to prepare the STL file that will be sent to the 3D printer.

The 3D printer "Prusa i3 MK2" will be used to Print the part.

The material will be PLA and its color is Black.

I will use colors if needed.

Ultimaker Cura 5.1.0 to slice the object

Design/Preparation Process

I designed the sketches of each part on Fusion 360
I did extrude To the sketches, then used revolve cut, and extrude cut.
Also added some features like fillets and thread.
Exported the bodies to STL files to be prepared on Ultimaker Cura software and get the Gcode to be sent for printing.

The timeline of the project

Then, I used Ultimaker Cura to slice the model to get it ready for printing as follows:

The layer height was 0.3mm cause I wanted the surface smooth.
The infill was 10% cause there would not be any pressure.
No Support is needed.
No adhesion is needed cause it will be on the bed plate.

I scaled the height down to match the requirements of the task( it was 81mm I changed it to 76mm)

Development/Implementation Process

I put the gcode on the card.
I preheated the plate.
I checked the bed.
I changed the filament and loaded the black filament
Selecting my file for printing from the SD card.
The machine started working.

The heating process.

The preparation process

Finally, the coolest pen holder

Proud!

Overcoming Challenges

This time it was a little bit easier, there were not many problems.

The challenges were as follow:

The sketch of the nut was not easier so I searched a lot and watched videos like:

printing the 3 parts together as one part so I sketched on the surfuce of the first body and so on.

Final Project

Modeling a 3D object with Fusion will be very helpful in making the air hockey paddles

Also, it will be very helpful in making the air hockey corners.

WOW!

Well, I fall in love with 3D printer and its magic.

literally, you can print everything.

For me, I managed to realize the dimension and use external tools to imagine the weight and height.

Coin for scale

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.
