Week # - 2

Assignment

Laser-cut plywood phone holder from my design

Let me explain more (ideation)

1-First thing this idea was in my heed for along time based on my experience during watching

content on smart phone

2-I imagend what if I take 2 side from apolygon of 10 sides to make the base of my phone holdera

look at the rocking chair moves up, down

This is my inspiration at first a phone holder moves up and down for giving me a different view angle but finally I stelled on 2 angels rather than more angles so I decided to take a polygon as a guide

This image showed my

idea of taking a polygon as a guide

Tool chain

1-First sketch by hand

showing the basic shape I follow
Helps me more with imagination processes

2- digitized sketch

After hand sketching, I used the software coreldraw to digitize my sketches

first digital sketch

second sketch

3-Fusion 360

Then I used fusion 360 soft wareto convert my 2d sketch into a 3d sketch, assembly my parts to visualize my sketch

4- RDworks

after visualizing my sketch I exported my parts in DXF file format to be obtained by CNC machine operating software (RDworks)

5- Machine

Bodor cnc co2 laser machine 300 what

6- Material

3 MM MDF foil coated is my choice cheap, has a great look and texure

Preparation Process

MY design consists of 4 parts or 2 pairs (side, back)

connected together using T slots, screws, and nuts

(4scrwes 10 MM long, 3 MM diameter and .5 MM bitch ), (4 nuts 3 MM)

Side sketch

Side extrude

Side apperance

After sketching and extruding our design we move to the assembly stage, at this point we join our model together and visualize it and take the needed action if we need to improve something or something doesn't work properly

Back sketch

this video shows our model after the assembly process

Autodesk Fusion 360 (Personal - Not for Commercial Use) 2022-08-15 06-22-33.mp4

After visualizing our model we export it as a DXF file format, open RDworks and import our model, and set our parameters.

parameter

speed : 40 MM / S

power : 15 %

Development Process

CNC co2 laser machine cutting a 3MM MDF

VIDEO for the cutting process

If you take a closer look at the red circle you will understand what I need to say the grove where the bottom of my phone rest isn`t big enough

So in the next prototype I will improve this point

Overcoming Challenges

1-When I was designing a phone holder in a shape like a triangle I can`t find the center of mass for my holder

so I decided to make a lo-fidelity prototype made of cardboard after the second one I find the nearst point

2- I was working with a different machine and I didn't know the right parameter

but after asking the machine operator he gives me the right parameter

Assignment Design Files

Side (DXF)

The general features, how it work`s

Just use a smartphone holder to improve your watching experience

1- The-first angle when you use a smartphone holder on a desk with a high

around 75 cm :100cm

2- The-second angle if you put your phone on a coffee table with a high of around 45 CM

Final project
