Frame design
This week we were assigned to create a custom design for a pair of glasses!
Honestly, I had no idea of what design or shape to go with, so I just decided to go with the flow and throw some lines until I came up with this design, which turned out to look like Rick's hair somehow😂
Maybe it's not that creative, but I like it 🤷
Side Arms
As for the side arms. I wanted something a little bit flexible, so I thought why not use a coil🤷
Tool Chain

Laser Cutting Machine for
front frame
3D Printing Machine for the holders
Designed both of them on Autodesk Fusion
RDWorks to prepare the laser cut (.DXF) file
Ulti maker cura to prepare the 3D (.STL) file
Printing material is PLA
3 mm plywood sheets for laser cutting

First of all, I looked up the standard dimensions of M3 screw to create suitable holes with a tolerance of +2mm
Front design steps
1) Creating the sketch of my glasses according to my facial dimensions, and positioning the screws' location in a suitable place
2) Extruding for 3 mm to match the wood sheet thickness
3) Editing the (.dxf) parameters to cut the frame
Side arms design steps
1) Created the flat surface to be fixed with a screw on the frame (3 mm thickness)
2) Creating the arm base extrude with a draft angle to give it strength
3) Creating the side arm coil using the coil built-in feature
4) creating the arm's end curvature sketch
5) Creating the solid part by sweep feature
6) Creating a hemisphere for the end by revolve feature
7) Using mirror feature for the other arm
8) Finally, editing the parameters on Cura so my printing time meets the limitation

When I went to the lab (Took my laptop this time😄), first thing was showing my designs to the technician to check for any errors (there were some as mentioned below).
Printing:
Took the .gcode on a flash drive and started the printing process
waited for the first couple of layers to make sure that the print is not failing since I had a risky design
once printed, I started cleaning my parts from supports and brim
Parameters:
10% infill
Gyroid infill
0.3 thickness
using supports / brims and support blocks
laser cutting:
copied the .ai file to a flash drive
imported my file to the machine's laptop to edit position and parameters
started the process after fixing the plate and positioning my cut on the machine, it took no time!
parameters:
Cutting speed 40 mm/s
Cutting power 45 watt
First layer of the print
Laser cutting the frame
3D printing parameters
Laser cutting parameters
Parts after finishing and assembly
Final look after painting the frame!
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?

Probably the first problem was what design to choose, but the actual problem that I faced was during the 3d printing of my sidearms.
When I tried to print it at first, we noticed that the flat part was not touching the build plate and was floating so we stopped the process, and I fixed the design by adding supports. And when we tried again the brim was not sticking to the plate, so my print was at a huge risk of failure, but thankfully it turned out well!
I learned about the "support block" feature to avoid using unnecessary supports.
Failed brim
Support blocker feature

Final project reflection
This week was more of a learning by trials; it gave a better understanding of how to take 3d printing into consideration while designing to avoid mistakes in my final project design of the 3d printed parts:
Playing balls
defending levers
