Last week I was inspired by a simple YouTube video while creating the mobile holder with cardboard. I then thought it might be a very practical and easy idea to fabricate in real life, as the holder can bear two mobile phones on both sides.
This week, our main software is Fusion360. We worked on much more details and we started designing complete and full designs by ourselves.
After finishing the design, I converted the design to .dxf format to be able to use on LaserCAD to fabricate it using the Laser Cutter.
I started by drawing the base of my design with the proper dimensions, following the same dimensions of the cardboard design.
This was the most important part of the whole design. It had to be long enough to bear two phones, one in landscape position, and the other in portrait position.
Final design after extrusion assembly.
Using Fusion360, I was still trying to familiarize myself with the environment and the tools. I followed most of the instructions mentioned in the videos, in addition to simple hints from our instructor. I made great use of constraints, sketch dimension, and mirroring while designing each part. I also used the fillet feature to give the parts a nice and smooth view. I used too many T-slots for a simple design. 7 exactly. But it was great to place everything right.
I drew the rectangle of the two shorter sides of the base, to help the phones not slip when using the holder.
I then extruded each part with 3mm thickness and assembled them using Joint.
After finishing the design:
I saved each part as a .dxf file.
I opened LaserCAD and brought all the parts together in one file.
I made some modifications to each part(removed additional construction lines).
I specified the right parameters for cutting ( Speed: 15, Power: 75).
I saved the file as .pwj5.
Fabrication time:
I sent my file to the lab's PC.
I opened it in LaserCAD and made sure I gathered them together as close as I can to not waste any wood.
I powered on the machine and sent the file for the final step.
I made sure the nozzle was at the right height and started fabrication.
After fabrication, I made sure everything fit in place, then I used 7 mm screws and nuts to finish it.
The whole design process was a lot of fun. After the first fabrication, I found the two triangular parts were not suitable for holding two phones together. They were very short and the angle was not right. I had to change the design again a little bit until I made sure it would fit. I fabricated it again and tried it in real life and fortunately, it worked.
The new one
The old design
Mostly I will use wood and laser cutting to construct my music box. I love this shape in the picture and I have some other designs that I might take as a reference.
End of week session was so interesting and full of challenge. We had to split into two teams of three, where each of us had to design a part of a chair design, and then assemble all the parts together. I was assigned to design and extrude the base part, and that was my first part to design by myself.
