This week’s assignment was to design a pair of glasses. The front frame had to be made from laser-cut plywood, and the side arms had to be 3D printed using PLA. We used Autodesk Fusion to design everything.
For my design, I decided to go with a gear themed steampunk-inspired glasses. I thought it would be a fun twist and something different from regular glasses. I’ve always liked the look of gears and how they move, so that’s what inspired me.

Inspiration
I was inspired by the design of steampunk-style glasses—like (this one to the right) and how the gears add a creative and mechanical twist to the overall shape. I really liked how they give off a cool, vintage sci-fi vibe. I figured, why not make something fun and unique?

I asked ChatGPT to create a themed like pair of glasses and settled on replicating some of the ideas the were made in this picture.

Which software/machines/materials did you use in the assignment? Why?
Which software/machines/materials did you use in the assignment? Why?
For the software I used UltiMaker Cura for 3d printing, and LaserCAD for preparing the files and cutting for laser cutter
LaserCAD
For downloading the file into the laser cuter
Autodesk Fusion
For 2.5d & 3d designing
For the machines used, our lab was equipped with Ender 3 Pro 3D Printer and El Malky ML64 Laser Cutter
For the material used 3D Printer used Orange PLA which is a biodegradable thermoplastic filament, and for Laser Cutting we used Plywood
The arms of the glasses were to be fixed to the front frame using m3 screws and nuts

I tried measuring the dimensions of my own glasses to get a reference but instead what worked better is getting a photo from google and importing it into Fusion as a canvas
Fusion crash counter for this project
I tried measuring the dimensions of my own glasses to get a reference but instead what worked better is getting a photo from google and importing it into Fusion as a canvas by selecting Insert > Canvas, then right clicking and calibrating the picture so I could design on it.
My design would revolve around a central gear in the middle of the lens with simple decoration and be held by thin cut lines that extend from the gears
To make this gear I had to search a little bit on how gears are made and came across these pages Calculate Module of Spur Gear and Basic Gear Terminology and Calculation which allowed me to calculate the needed dimensions for 33 tooth gear
Lens design after adding the supporting lines for the gear and inner piece and the look of it in 2.5D after extrusion.
Some numbers to keep things in reference:
Distance between the 2 centers of the glasses is 62mm
Distance for the nose area is around 11.2mm
Length of the whole design is 140mm
Length of the full arm of the glasses is around 150mm
Distance from the from the front of the glasses to the ear part is 104mm
Screenshots of the sketches
After finishing the front-frame I started working on the arms using the same method of importing a canvas, calibrating and then tracing it
I made the arm by making 2 sketches extruding them then combining them into 1 part
The piece that would be connected to the front-frame was made by projecting the circle from the frame and making a 3.3 diameter circle for the 3mm screw, the 0.3 difference is due to PLA shrinkage after printing.
The last thing that remains is some minor tweeks to minimize supports use and make sure the model prints without failure on the 3D printer
By using Fillet and Split Body I am able to remove unnecessary pieces and flatten the shape.

I finished by adding this cute small gear shaped face in the middle of the front panel
ALL PARTS ARE FULLY DEFINED
some screenshots had profile unchecked because its easier to see like that, others just had fusion bugged.

I didn't know about "dxf for fusion" extension so I right clicked on every sketch in order and exported them as dxf
Implementing the sketches in LaserCAD was straight forward, I imported my sketches and aligned them, Double check the Power and Speed and headed to the lab to cut it.
Color - Job - Speed - Power
Black - Cutting - 15% - 75%
Red - Speed Cut - 250% - 50%
Blue - Engrave - 250% - 60%
Green - Light Speed Cut - 250% - 30%
Uploaded the files to El-Malky laser machine and aligned the origin to the suit the plywood sheet, then hit print and waiting for it to complete.
The print came out great from first try.
3D Printing Prep
3D Printing Prep
Exporting the files is rather simple, I right click the body and click "Save As Mesh" it gets saved as .stl and ready for the slicer
Same as the laser cutting machine, I transferred my .gcode to the SD card and choose it to start printing
The model was designed to be laid on its flat side to minimize supports and picked 25% for the infill and 0.2mm for the layer height, lastly choose normal supports not tree supports to support the holes, tree supports took more material and didn't look as promising as normal supports.
The model came to be around 7 grams of filament and would take 1h 6min to finish printing.
Exported the .gcode with the following settings:
Nozzle temp: 210 C
Bed temp: 60 C
Supports: yes (normal)
Time: 66min
Weight: 7 grams
A nut and a bolt were used to secure the arm with the front frame
Aaaaand we done.

I asked for feedback on minimum line that I could cut and I got recommended a minimum of 1mm to be cut well and it worked first try.
Overcoming Challenges
Overcoming Challenges
When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

When making the gear shape I had to research it first because it wasnt as simple as i thought and after coming across these pages Calculate Module of Spur Gear and Basic Gear Terminology and Calculation I was able to continue with the design
Another issue was trying to define the length of a pattern but not from the original sketch that created it, which causes a loop and crash the program.
I had around 20+ crashes as the project was recovered once in a bad spot and got corrupted ever since. I would recommend to never continue building on corrupted files it will bite you at the end.

I learned this week the tolerances of the machines and what are the minimum dimensions that a model could support, this is sure to help me in my final project.
WOW!
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Fusion of course was the coolest thing its a simple software the could easily make an idea into a real thing in a couple of hours.

If you checking this project out use the Project link and if you wanna just test it or check the files, you only need Full-Front-Frame.ai and both the .stl files
Rest were made to fix some cosmetic issues that happen when importing .dxf file into LaserCAD and are not needed
