I wanted to generate a new design thing for the glasses so i started at this process with:

First, 

for search: I made a visual feeding to see different designs and to make my brainstorming process. so, i usually using Behance platform and Yandex images for this process 

and i searched for the glasses measurements to Take it into consideration while designing my own one.

for the design,

i used fusion 360 for make the design.

then, RDworks and Cura for design preparation and slice.

for the machines:

laser:

El Malky ML149 CO₂ Laser Cutter for cutting, and 3mm plywood as the material—it’s sturdy, clean to cut, and perfect for detailed designs.

3d:

Creality Ender 3 Pro to print it, and PLA filament as the material. 

Nuts and bolts: for joining the parts 

after sketching on the paper and defining the dimensions i started to make it on fusion:

first, I open a new file and adding a new component to start sketching.

then I started with the face, and I made it fully defined sketch after that I extruded it with 3mm distance

after i finished the face i started to make the sides with adding a new component and i sketched it on the back of the body, i added a placement for the nut as captive nut then i extruded it 7 mm, after the extrude i added a sketch on the front side to add a slot (m3) [ circle with 3mm diameter]

then i copy this component and edit the extrude to be -7 mm to make the other side 

and the same as the face i added fillets to reduce the sharp edges

after I finished the design process, I wanted to assembly the 3 parts together and to add some appearance

so, we finished the design process 

we need th export the files for 3d printing and laser cutting:

for the body (2d laser cutting) :

i used the extension for export it to laser cutting i selected the sketch then choose it and edit its parameters. 

for the sides (3d print):

i choose the 3d option from the (file) list 

then i choose the body i wanted to print and previewed it 

then save it as STL file. 

now, we designed and exported or files, it's preparation turnnnn!

for the 2d laser cutting:

 i opened the dxf file we exported at RDworks,

then, started to edit the parameters of it:

they all lines were cutting lines, so it was: 40 for speed and 45 for power

then save it as plt 

for the 3d printing

 i opened the STL files we exported at cura to slice them,

actually i needed to rotate them on their back to reduce the time it takes from 1h to 34m for each side!

cause, at the first it was 2 times taller than the back and the two statues needed a support because of its curves.

the infill was 20%, support was touching buildplate, layer hight was 0.2 and the adhesion was on

then save it as gcode

for laser cutting:

1. Prepare the Material: Place the material securely into the machine.

2. Select the File:

   • Navigate to the Files section.

   • Choose the appropriate file name.

3. Set Origin and Frame: Designate the origin point and adjust the frame as needed.

4. Close the Machine Cover: Ensure the cover is properly secured before starting.

5. Begin the Process: Initiate the machine to start the operation.

it took me less than 1minute.

for 3d printing:

select the printer i want to print at

clean the bed 

upload the file using USB 

select print from usb

then choosing my file just it.

1. "رطوبة اللوح بتحتاج نزود ال power +5 علشان يقطع كويييييس"

2. for captive nut or the t slot we need to add a tolerance عشان الماشينز فيها نسبة خطأأأأأ

3. لما تستخدم المبرد متنساش تلبس الجلافز عشان متتعورشششش

the capitive nut at the glasses side was a little bet narrow for the nut to be in it cause i did not caculate its tolerance, so i needed to use files to add some space mnually! (اكتر حاجة مملة وصعبة وبتوجع الايد في الحياة ف معلش زود رينج التوليرنس خليها عليك)
