Week #3 - Journal

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)

This week, I will design the pen and pencil holder that consists of multiple 2.5D parts and assemble them using T- slots and captive nuts to hold different stationary items and fabricate the 2.5D parts using Laser Cutting.

I was inspired by the mobile stand model with T- slots. I thought to make one and add a middle and front panels to it

Tool Chain

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

I used fusion 360 to design all my panels.
then i pressed "export dxf for laser".
Next, I will open the .dxf file using laser cad and print it on laser cutter.

the material used is wood sheets (plywood) with thickness 3 ml.

using fusion 360 to design my panel sketches

I will use El Malky ML64 CO2 laser cutter in designing my pencil holder.
The design will be drawn using cut tool included in the laser cutter machine. Plywood with 3mm thickness will be a good choice for my design.

I will use LaserCad software in my designing as it's used for designing and doing adjustments of .dxf extension files for the purpose of Laser Cutting

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?

pencil case design on fusion 360

using fusion 360 to assembly panel compartments

First, I opened fusion 360 , created a new file and saved it.
second, I designed each panel on a separate compartment.
Then, I extruded them to 3ml thickness ( like our wood plates thickness)
I assembled them at the end by attaching one side of T- slot in one compartment to opposite side that it will enter in it in the other compartment
i repeated this step till i all the sides were assembled together, and i changed the appearance to oak.
At last, i pressed "export .dxf for laser".
Next, I will open all the .dxf file using laser cad and put all the panels beside each other in the same file and fabricate the panels on laser cutter machine.

Finally, i will assemble all the panels by attaching them with the T- slots and M3 screws and nuts.

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?

After i finished all my design and assembled it, i saved each sketch for each face alone (by pressing "export dxf for laser")

then i opened my sketches on laser cad and put them all together on the same page. (by pressing ctrl +i)
i pasted 2 copies from front panel and side panel, and added middle panel and bottom panel)
I adjusted the parameter needed (cut with power 65 and speed 10)

then i pressed download to upload the file on the laser cut machine, i put my wooden sheet, adjusted the origin and the box (place of printing) and pressed start

the model panels took 6 minutes in fabrication

finally i assembled all the wooden panels together and put the screws and nuts.
now my pen stand is ready, i put pens and pencils in it

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?

yes, I asked feedback and help from my instructor yasin while designing on fusion 360, and he guided me and answered my questions.

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?

I made a mistake in my design and found it after fabrication 😀
All T slots were cut because i left the line in the middle of them, so the machine cut the line.

So the solution will be to use Trim to remove the line in the middle on T-slots, by that the machine will cut the frame from outside and i will keep the T-slots.

Final Project

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

Title of Media

i will design the box that i will put the candies in it using laer cutter by making compartments and assemblying them using T slots, screws and nuts

WOW!

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

i attended extra session with yasin, and learned about kumiko japanese design
i also learnt about how to use inkspace to convert ready made pictures to .dxf extension to implement them using laser cad application

I used what i learnt and made kumiko coaster

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.

I'm training my elementary students to attend FLL competition , so they designed a cool submarine using lego spike essential kit and an extra kit
and teaching them how to code the motors and color sensor
