Week 2 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What were you inspired by?

This design was my inspiration, I love the fact that it holds the phone in 2 different ways, and also I like the pattern on it.I edit it a little bit because i wanted to assemble this using screws and nuts so I have to make some changes as I will demonstrate it in design process

Tool Chain

Which software/machines/materials did you use this week? Why?

Fusion 360

For designing process, I used Fusion 360

LaserWorks

To prepare the mobile holder to be cut by the laser machine, I used LaserWorks software.

Laser Cutter Machine

I used the laser cutter machine to cut the mobile holder,

Medium-density fiberboard

I used Medium-density fiberboard to be the material to be cut by the laser cutter machine. (3mm)

Manual electric grinding machine with emery wheel

I used it to remove the burning marks from the mobile holder parts, after cutting.

screws and nuts

I used it to assemble the parts of the mobile holder together.

Design Process

Explain the design process of your assignment. How did you use the tool/software to design and/or simulate your assignment?

first: I took my mobile measures to make sure that the mobile will fit perfectly on the mobile holder.

I drew the first part on fusion 360, the outer rectangular has the same dimension as my mobile (170x80), and then, I drew the inner rectangular to be smaller with enough distance to drew the T-slots (55x145), I also drew 2 circles (10mm D & 15mm D) and then, I applied the rectangular pattern and trimmed the unnecessary lines to get the pattern I wanted, I rounded the edges with 2mmD just to make sure the edges will not be sharp.

and then I drew the sided part, I had one side dimension which is (170mm) and I was knowing from the picture, it will be 90- degree angle with the second side and the third side will be touching the ground so, this how I drew it and calculate the second side value. (112.793 mm), I also rounded the edges and applied the rectangular pattern as I did with the first part.

by knowing the missed value of the second side, I drew the third part, the outer rectangular has the value of (80x112.793), I did all other things the same way I did with the first and second parts, and I drew 2 circles of 3mmD to be the holes of the screws.

This is the part I added because I knew from the picture if I assemble the parts with screws and nuts, there will be a slite height from the 2 sides and this will prevent me from making the same shape as the picture with 2 parts that holding the mobile being attached to the 2 side triangular parts, because it will be far away from holding the mobile in portrait position, so I made this two separate parts and I made slots for part 1 and 3 to be fitted in it.

All parts

I put all parts into new design, and extracted the DXF file to be opened by LaserWorks.

Laser Cutting

To prepare the mobile holder to be cut by the laser machine, I used LaserWorks software to define which lines will be cut and which will be just engraved by defining the speed and power of each.

For cutting: speed: 22 mm/sec Power: 65%
For engraving: speed: 300 mm/sec Power: 25%

and finally, I saved the file with the .rld extension to be loaded to the Laser cutter.

Fabrication/Implementation Process

Explain the fabrication/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

In order to cut the mobile holder parts, I used the laser cutting machine.

First, I loaded the DXF file to the machine and made sure that the wood board is in the right place, and I set the origin point to start cutting from it and then, I traced the framework to make sure that the wood board is enough for the design, and then I choose the file to start cutting process.

I used a manual electric grinding machine with an emery wheel to remove the burning marks from the mobile holder parts, after cutting with the help of the FabLab specialist.

Video

I assembled the 2 parts with screws and nuts.

I placed the 2 parts into slots of the fourth part.

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 project?

When I have drawn the circles and applied the rectangular pattern, I missed to modify the distance of extent, so it looked like half circles in the bottom, this affects the final shape. I figure it out after fabrication, unfortantlly.

At first, I was not able to extrude this part, so I searched and founded the solution in this article.

Something went wrong when I cut this shape and the holes of the screws weren't be cut so next time when I go to the lab I will use the drill to make the required holes.

WOW!

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

being able to make a mobile holder from A to z !!

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: Pre-activity, examples, exercises, or any mini-projects.

Being able to draw the parts of the catapult and assemble all parts via joints to form the final shape.

First, I drew all the parts of the catapult on Fusion 360 according to the given dimensions.

Then, I extruded all the parts and assemble them via the joints.

Voallla :)

looking so real !!!!
