In this week we were asked to design a mobile holder that is composed of 2.5 D components. Firstly, I thought about designing a holder that looks like the first picture, but after sketching it and trying joining it on fusion 360, the output didn't satisfy me, then, I decided to stick to a basic mobile holder as the second picture with the proper dimensions to my mobile
-Fusion 360 to draw the mobile components; as it has lots of tools that can help me conduct an advanced sketches, and it has "extrude" and 'joint' properties that are useful in simulating and joining the design parts in the 3D word
- Laser work software to prepare the rld file for the laser cutting machine
I first draw the components of the first design, but the output wasn't as I expected and it totally missed up. So, I decided to redesign the holder from scratch and take care of the dimension of each part, and how it relate to the other parts and to the whole function of the holder to not replicate the mistakes in the first design.
In the second design, I sketched it in 3 parts; the back, the base, and the supporter for the back. The back dimension was the same as my mobile, the base length was 3x the thickness of my mobile to hold it properly, and for the supporter, I used Pythagoras theorem to calculate the proper length of the supporter, so that the back angle be at least 60 degree.
In all the parts I began the sketches with half the design then I use the mirror tools to finish it. I start by drawing a rectangle then draw two fixed construction lines in the vertical and horizontal midpoint to make the whole design rigid.
Regarding the t-slot, I drew it separately, then I made a copy of it and transferred it to the supporter sketch.
At the end, I added a PNG image and texts to the back part for decoration purpose, to give it as a gift to my friend

Firstly, I exported each part of my design to the DXF format, so that I can manage them in laser cutter and assign for each part the proper cut and scan properties. Then, I saved a rld file format for all the design parts together. Finally, I downloaded this rld file to the laser cutter machine and the cutting process took around three minutes
During the end of week session while we was discussing the challenges that we faced during practicing with the midweek videos. Doaa Azooz (my peer in the group) was extremely helpful and give valuable notes for fixing the problems that we faced in sketching and extruding different designs, it was really helpful for me!
I got stuck at sketching the first design, I realized that I didn't plan well for giving the proper dimensions for each part, so I decided to pause and begin from point zero. This time I take in my consideration the dimensions of each part and why it should take those dimensions, and for the holder to have the proper standing angle I used mathematical calculation to get the suitable length of the supporting part, so that the mobile be at a suitable angle.
So lessons from my mistakes are:
1- give yourself time, so that if you got stuck you can search for a proper solutions without being forced to make something of less quality
2- when you design something always analyze every single dimension and why it should be that way not the other, so that you will have a clean design and things doesn't miss up
I learned how to precisely sketch and analyze any design that come to my mind, this is a crucial skill that I will use in designing the different parts of my final project
The coolest thing is that I now can sketch anything that I want with the aid of my best friend (my laptop :D) cause I don't have this skill in my hand and I didn't imagine that I could have it by any mean!
