The idea of the project is to make cool glasses. It consists of two parts. The glasses part is made of laser cutting and the hangers made of 3D printing.
I inspired the final design from these pictures.
Fusion 360 logo
For the design I worked on Fusion 360 to get the design as Cura and Laserworks are not design programs. Then the files are saved as DXF and STL files
For 3D printing
Software: Ultimaker Cura
Machine: Prusa i3 mk2 3D printer
Material: PLA

Design of the glasses on fusion 360
First I took the dimensions of the real glasses. Then decided the design I want. I started by drawing the main circles of the frame then draw the link between the two glasses. The design took many tries on fusion as fatal mistakes happened and cannot be corrected. Then I started to design the glasses' arms on fusion by the same steps. I took the dimensions of the arms of the real glasses and starts to implement the design of the arms.
The sketch is fully defined on fusion as the glasses is mirrored on the origin

Extruding properties
This photo shows the extruding properties for the glasses. I selected the shape then removed the parts that won't be extruded. The extrusion is set to be 3mm as the wood thickness.

The glass holders are sketched on fusion and fully defined. The first holder on the right is draw with the dimensions and mirrored through the origin to get two glass holders fully defined.

The fully defined sketch for glass holders
This is the steps to get the final glass holders:
1) The sketch is selected to make a extrude with 10mm.
2) The upper sketch of the first glass holder is selected to draw a 10*2mm rectangle.
3) This rectangle is then extruded with 7 mm.
4) The upper sketch of the second glass holder is selected to draw a 10*2mm rectangle.
5) This rectangle is then extruded with 7 mm.
6) The front faces of the extruded rectangles is selected to draw a 3.3mm circle diameter for the holes of the M3 screw.
7) The holes is selected to be extruded cut by -7mm.
8) The edges of the holders are selected to be filleted by 2mm.
1) From modify menu select appearance
2) From appearance menu search on plastic and from fusion library menu select the color.
3) The color selected is yellow.
4) To get natural appearance to the holders select the arrow under the axis.
5) Change the state from orthographic to perspective to get more natural look.
To get the STL file:
1) From the left menu select Body 1
2) Right click on it and from the menu select save as mesh
3) From save as mesh menu select STL binary and the unit Millimeters then save.

Design of the glasses on LaserWork and Cura
The implementation process took place on both Cura and LaserWork.
I saved the file of the glasses' frame as a DXF file to insert it on LaserWork. The design is inserted and the adjustment phase took place as I deleted the overlapped lines and the extra lines was also deleted and then decided what to be cut from the sheet.
The arms' file was saved as mesh then I select 'STL Binary' then high then ok. The file was inserted on Cura. The layer height was set to 0.2 and 10% infil and brim is selected.
File on laserwork
The DXF file is inserted on LaserWork. The extra lines are deleted. From the upper menu select delete overlap to delete any overlapping lines to make sure that the wood would not be burned.
The shape after all the editing. All the lines are selected to be cut with black lines. The speed id 25 and power 65.
Final shape
The STL file on Ultimaker Cura:
The two holders are with infill 10%, without supports and with adhesion.
To get more details go to the custom setting:
The layer height is 0.2mm, infill 10% with cubic subdivision, the material heat 215 and brim is selected.
The time taken was 1h and 19 minutes for 13 grams.

Final design
When the arms were printed, the print moved from its place as the surface area was small to be mounted to the bed.
The specialist in the lab suggested to use adhesion then brim to mount the arms on the bed.

The connector between the two glasses is very thin and may cause the breaking of the glass.
The instructor suggested to make the connector thicker to avoid this issue.

To decide the right dimensions for the project as the incorrect size lead to waste of materials.
I learned to get the dimension clearly and to imagine it in my mind to get the most accurate shape.
Robot Book mark (Baskoota)
We made a robot bookmark from two parts. The first part is the face of the robot was made by 3D printing. The second part is the body and it is made by laser cutting. I decided to name it Baskoota.
