This is my make-through for the week's assignment.2 Grab a cup of coffee!

BACKGROUND
BACKGROUND
I chose to design the Bluetooth,speaker, because my friend and I love to listen to quiet music at night. After my speaker is damaged, we can no longer listen to the music as we used to, and that caused great frustration to my little friend who suffers from insomnia because of that, it was this loudspeaker. It is like a late-night story that makes him sleep long and does not think of anything. I felt sorry for my sad friend, so this idea came to
OBJECTIVE #1: think how to fabricate
OBJECTIVE #1: think how to fabricate
Step 1:how to design a new speaker by the allowed digital fabrication process
Step 2: making the design compact and easy to use
Step 3:deploy a screen for showig the user what is playing now ,volume percentage and time .
Step 4:deploy a bush button to turn off/on the speaker
Step 5:put a power jack to supply power to the speaker
Step 6:deploy a Bluetooth module in the circuit to control the speaker
OBJECTIVE #2: enclosure parts designing and components assembly
OBJECTIVE #2: enclosure parts designing and components assembly
Trial #2 :designing the enclosure parts
Trial #2 :designing the enclosure parts
Step 1: I intend to fabricate the corners of the enclosure by 3D printing which its the easiest way to make slots in multi-direction and subject
the enclosure sides together
Step 2:designing the long and short sides of the enclosure then fabricate them by laser cutting
Step 3: then I design the back and front of the speaker to cut them in a laser cutting machine and I make a specific position for the electronic components in both front and back
Step 4: I intend to use side slot nut for joining the enclosure sides together so I cut two slots in the 3d printing part to put a nut into it
Step 5: i intend to colour my design after manufacturing
to make all the components same in colour as well as using white acrylic to make it look good and engraving brand name (JBL)
Step 6: I go to grab cad to import the bush button ,mini screen and power jack
Step 7: finally I open a new assembly to join the parts together as shown
OBJECTIVE #3: fabriction prepration
OBJECTIVE #3: fabriction prepration
Trial #3 :how to prepare parts for fabrication
Trial #3 :how to prepare parts for fabrication
Step 1: for parts that need to be fabricated in laser cutting machine I open a new project in laser work software and then import the file which saved as DXF extension to identify each vector for the machine and export an RLD extension file
(cut, scan)
Step 2: for the corner which required to be fabricated in a 3D printer I save the file as STL extension then I import it to Prusa slicer to specify the printer properties and material

I face a problem while design as it was how to make an enclosure with good finishing and easy to assemble and disassembly. I think first to use snap-fit but I see that it will not be a good idea because there may be high load in the speaker so I intend to use side slide nut and screws for joining the sides of the enclosure together
CONCLUSION
CONCLUSION
What I learned this week is...
1-i learn in this week how to apply the design technique of screw and nuts joints for manufacturing products in laser cutting
3- I know how to mix manufacturing and joining techniques between laser cutting and 3d printing
4-now I can use Prusa slicer to estimate the time required and the mass of the material that will be used to fabricate a design in a 3d printer
5-knowing how to import files to laser work software to upload it to the laser cutting machine
