Week 2

Cool Glasses

My task this week is to create cool glasses with mixed designs 2D and 3D designs, the body will be a 2D design and the arms will be a 3D design, after doing some searching, I found the coolest design is my glasses design 😎😎.

So I grabbed my caliper and started the measurements.📐📏

In this task, I'll use Fusion 360 in designs, then cut the body on the Elmalki laser cutter on 3mm plywood using Laserworks software and print the arms on the Prusa i3 MK3 3D printer after slicing with Cura Software with cool color PLA filament.

To know how I did it, follow me to the next few steps.

Open Fusion 360 software from your computer

and do the following steps as shown below

first you have to save your project "Click save" to save it
write your project name and choose the location folder
click on Create Sketch to start sketching

The 2D Part

In this part, I will build the glasses body to be cut on the laser cutter

After creating the sketch you have to choose the dimension that you will work on

since we will sketch the glasses body I will choose the 2D dimension X, Y as shown in the left figure

Now I'll start sketching

from the top toolbar, click on Create and choose the 3-point arc
set the dimensions " the distance between points and the curve diameter "
then identify the arc to the origin point

🚩▶️Important tip

You have to identify everything you sketch by identifying its " length, angle, diameter, parameter, etc... " to the origin point or shape already identified.

Sketching the rest of the glasses by adding a circle and identifying it

From modify top toolbar choose Offset and set outer offset for 3mm

It should appear like this if we do it right and it should be identified since the first shape is identified

Now I'm going to create the part that will hold the arm

I'll draw a rectangle with a 3mm circle to hold a 3M nail, then I'll modify the rectangle edges with the fillet option as shown in figure

It should appear like this if we did it in the right way

Select your drawing, and from the top create a toolbar click on Mirror to mirror your design.

choose the object that you want to mirror then choose the mirror line, and press OK

you should see this figure "Don't worry, we will identify it later "

From the Create top toolbar choose slot and create 3 point arc slot, draw the bridge between the two lenses

Now after drawing the bridge trim the extra lines from the modify toolbar and identify all lines and shapes

all lines should be black as shown figure

All designs set, click on Finish Sketch on the top right toolbar

select your object and click on extrude from the create top toolbar, and extrude it for 3mm then press ok
now we need to make the design look like wood, from the left tree right click on the body and choose the physical material
choose the material by dragging it to the object

Your design should look like the one shown figure

Now we need to cut it on the laser cutter

from the left tree right click on the object from the sketches choose " Save as DXF" and save it on your computer
to be ready to handle it with Laserworks software

Import the DXF file to Laserworks software

double check your size and lines
choose all lines to be cut
set the power to 50 and speed to 30

cutting on the laser on the mentioned parameters before

and here is the final body it only took 40 sec 😀

The 3D Parts

In this part, I will build the glasses Arms to be printed on the 3D printer

In this step, I will build the glasses arm

I'm going to start with the left arm and mirror it to the right one since the design is mirrored

first I need to sketch the arm in a new sketch, so from the top toolbar

choose construct then click on offset plane
click on the surface that the glasses arm should be then click Create a sketch

🚩▶️Important tip

you will repeat the previous two steps for each sketch

Draw the arm base to attach it with 3M nut with the body

finish the sketch and extrude it with the extrude option for 3mm

Now create a place for 3M nuts set the nut size to 3.1 to fit the nut into it

Extrude the nut design to -1 mm to make the nut fit in it

Sketch and extrude the rest parts of the arm as shown at the top figures, and remember to mirror every sketch to build the right arm

In this step, I will build the curved part of the arm

first I had to create a new offset plane at the inner side of the arm and create a sketch on it.
draw the curved part with a 3-point arc
Then I'll use the Loft option from the Create toolbar as shown next steps

Draw the end sketch at the right place " new sketch and offset plane" according to your measurements

From the create to toolbar choose loft and follow these steps

click on the centerline first
choose the two profiles you want to draw the 3D shape between
choose the centerline as shown and click ok

and now the final design after applying all sketches and constraints on the other arm

Apply the physical material on the arms, and apply some modifications on design" fillet and chamfer "

Here you go, your final design 🤓

to export the design as STL file, right-click on the design body file and choose save as mesh

set the format to STL Binary, choose high at the refinement then click ok

Repeat these two steps on the second arm

Open Cura software and import the two designs, put them on the right side and right orientation

set the parameters for printing, and layer heights to 0.2, infill to 20%

set the support to base only

slice the design to know how much time and weight it will take

it will take 52 min and 6 gm of filament

save the file as gcode

browse your files and print, confirm the bed and nozzle temperatures and wait for your first layer to be done

The first layers are done, almost finished 🤩

The last shoot, before the electricity down 😭

here is the final design after removing the support

Assembling parts

In this part, I will present some photos for the final look after assembling the body and arms

Assemble the two parts using a 3m screw and nut

The nut didn't fit in the designed hexagon, because it shrank from the heat

Finally after assembling all parts

and the coolest glasses look like my glasses

Challenges

When I tried to build the curved part of the glasses arm, I tried to create a loft with a specific path, and after searching I found that I could use the centerline option at the loft
