Design inspiration:
Nothing specific, except for those random designs I checked online and the watermelon one captured me to design, for how recently watermelon has been used to symbolize Palestine, as some countries that denied its existence now know it well through the help of that symbolism.

Which software/machines/materials did you use in the assignment? Why?
Designing:
The designs are implemented through the AutoCAD software (Fusion 360).
Laser cutting:
The software used is RDWorksV8. Plywood of 3mm "4 layers" (First picture on the right for plywood with the software icon).
The used machine is a proudly made in Egypt laser cutting machine El Malky ML149 Laser Cutter which operates by CO2 fumes that ionize into the laser beam.
3D printing:
The software should've been Cura's latest version, but because my laptop is a bit outdated, so I'm using Ultimaker Cura 4.13.1. PLA (Polylactic Acid) filaments are used in Prusa MK3 3D Printer.

3D Printing
Screenshots of the first sketch
Step one: (2D Sketching) Using Fusion 360, I started by saving the file, creating a new sketch of a centered rectangle around the origin point, and fully defining its dimensions into the glasses arms which are around (14 cm). The dimensions of the rectangle are 10cm* 0.11 cm. By adding a centre to centre slot, I added the curved part of the arm of a length of 4 cm. Finally, I trimmed the unnecessary lines to reach the final figure in the last picture.
Step two (2D into 3D): After finishing the sketch, I extruded the whole figure, and then on the terminal side, I sketched another rectangle (2-side rectangle) and it was easily defined as the sides of the extruded figure were fully defined. Afterward, I extruded the new rectangle which was meant to fit the M3 screw, but it needed to be joined with the other long arm, so I sketched another square on the side facing the arm to enter it through extrusion (join). To print it properly and avoid any sharp edges, I used the fillet feature as shown through the timeline picture for all the edges. Finally, I made the space for the M3 screw using the extrude cut feature after sketching a circle with 3.3 mm for the screw and nut In the end, I copied the whole 3D figure, to show the two arms.
Exporting the file into STL: Using the screenshots below, I simply followed those three steps, but make sure you get the drop-down menu of step one through the body you want to convert into STL and get it ready to be sliced using Cura.

Step one: (2D Sketching) Using Fusion 360, I started by saving the file, creating a new sketch of a centered rectangle around the origin point, with dimensions of 13.2 cm*7 cm, and the line is set by a constraint to intersect the rectangle at the midpoint of each length. Sketching the triangle at the left side is done through the polygon sketch (circumscribed polygon), with setting its diameter to be of the lens (5.2 cm). Then, I diminished the diameter of another circle to be sketched inside the triangle with a bit smaller dimensions (4.2 cm). I also used the fillet feature to make the edges of the triangle less pointed. I intended to draw a three-point arc slot on the right side of the triangle to represent the bridge between the two lenses. Using the midline of the large outlining rectangle, I used the mirror feature to copy the sketches to the right side. For all the dimensions to be fully defined, it needed multitudes of measurements and constraints, as I wanted to define them all after trimming and breaking all the lines and arcs I sketched. (The screenshot of the dimensions is attached below in step two).

Step two (2D into 3D): After finishing the sketch, I extruded the whole figure, but I realized that I forgot to sketch the watermelon seeds and the two 3mm holes for the M3 screw, but it wasn't an issue to be defined.
For the fact that the watermelon seeds take an irregular shape that was drawn by the spline tool, they're, unfortunately, the only undefined part of the sketch. I copied each and pasted them accordingly, then they're all mirrored to the right side through the line through the midpoints (mirror plane).
The extrusion was only for 3mm, as this is the exact thickness of the plywood sheet.
At the end, I gave the 3D body a wooden appearance to seem somehow real.

Laser-cut implementation:
Using RDworks before cutting, I added a line first that outlines the upper part of the watermelon frame, marked the parts to be cut, the parts to be scanned (engraved), and those to be speed cut, and I exported the file into ai format, as the laser cutting machine is connected to a computer that doesn't use RDWorks.

Slicing was easier because only added touchplate support.
So, through the shared pictures and videos, I printed the other 3D part of week one's assignment, due to an outage in the 3D printer in the previous slot, that's why the printing time took nearly the entire 3D slot for week 2 (1 hour and 19 minutes).

I struggled and sought for my instructor's help through Slack, as one of them suggested that I can extend the L-shaped part to fit the M3 screw.
Also through the supporting session through Zoom, my own instructors changed my way of thinking about designing the arm, because I insisted on using an extra feature that was not necessary.
As usual, I'll most probably mention my gratitude to every single instructor for Maker's Diploma.
My peers and I always share what we know to help, so this is also something to be grateful for.

Removing the printed support was both scary and challenging, as the Fab lab instructor taught me how to use the tools that remove the support gently.
I used the fine file and the tweezers to gently remove the excess support parts without ruining the shape of the object or breaking it.
Defining the lines was also a challenge, but as I was learning and reflecting through the self-study videos, I learned how to use the constraints to define the lines with respect to the origin and/or measure the dimension from the origin or a defined sketch to the origin with respect to the undefined sketch, and by that time fully defining any line was a lovely challenge, like mathematical equations at school.

My final project will mainly depend on designing the walls and the greenhouse itself through Fusion 360 to create what is to be cut by laser.
This week is indeed crucial to design what I exactly want using Fusion 360.
WOW!

Designing the combined bookmark was such a wonder, because I've never visualized a bookmark with such a shape.
