This week's assignment is challenging, as we are tasked with designing pen holder that 2 compartments on one base, with at least one of them closed with 4 faces, to hold different stationary items.
I browsed through different designs and came across a cat-shaped pen holder that caught my interest—I'm really looking forward to creating it.

Designing Pen Holder steps.
I saved the file and named it.
Create the first component which is the back of the pen holder.
Dimensions used: - Height 104 mm and width 200 mm
3- Draw 2 places for the screwdriver and captive nut.
Extruded the shape and choose an appearance.
Draw first side with dimension 80 width and same height.
Repeated drawing 2 places for the screwdriver and captive nut.
Extruded the shape and choose an appearance.
Join the two sides.
Copy the side to make a middle side.
Draw a front side with a cat face with length 200 mm and half height 104 mm and half 52mm to fit the face of the fact then extrude it and change appearance.
Draw the last short side but with dimensions 52 height and 80 mm width.
Use project to draw the base over the sides with 6 T slots to fix al the sides. Dimensions 200 mm length and width 80 mm.

Lasser Cutter Process
1- First, I downloaded and saved all the files in dxf format, then selected black as the cutting colour.
2- I booked a slot for printing and visited the lab to do.
3- I imported all my files together then I checked the dimensions of the total and dimension of the wood sheet.
4- I used 40 for speed and 45 for power.
5- I then downloaded and saved it again.
6- Choose a wood sheet and placed it and fixed it from the sides.
7- Checked the focus of the machine.
8- I press start on the machine then press file then choose my file then enter.
9- Adjusted the arrows and checked the area exactly where I want to print in.
10- Press origin then frame.
11- Close the cover of the machine and finally press start to cut my design.

Download then name the file.

Prepare and fix the sheet for cutting.
Choose the file.
Adjust the frame and choose origin.

I discussed with my instructor the problem I encountered with the side lengths not joining properly after extrusion. He suggested increasing the size of that side, but when I tried, it didn’t solve the issue. I then revised the sketches again, and this time it worked.
I also asked one of my colleagues how to place all the sides of the pen holder together for printing at one time. He explained that the way to do this is by importing them together and keeping them close, so they fit properly during printing.
2- I encountered an issue when drawing the base with a width of 92 mm, as it didn’t align properly with the other sides. I tried fixing it by adding 6 mm, but it didn’t work. So, I redesigned the entire piece with dimensions of 98 mm and 225 mm for the base and eventually discovered that the issue was caused by the extrusion of the designs.
3- After adjusting the shape for printing, I found that the dimensions for printing on RDWorks didn’t fit the sheet of wood I am using. The lab specialist advised me to cut all the pieces except the base and print it separately, which I did that, and it works perfect.
What I’ve learned in designing from scratch using Autodesk Fusion 360—even though it was my first time—will definitely support me in creating my final project more easily.
The coolest thing was being able to design the eyeglasses entirely from scratch, print and cut too. It’s my first design project and a major achievement for me—but definitely not the last😉
