For this week, our task is to design a handphone holder using fusion 360 with the help of parametric.
Why use parametric? It will allow us to easily modify and tweak designs on the spot by adjusting set parameters that were pre-setted by us.
For simple designs like the one below, the use of parametric may seem futile as all the dimensions can be easily identified, but for complex 3d models where some parameters are inside the model and cannot be easily identified by the sketch., the use of parametric will come in very handy.
L= Length
W= Width
H= Height of gap
I then proceeded to make a sketch of my design, separating my handphone stand into two components that will be pieced together after being laser cut.
It is done assuming that the material that is being cut to be 5mm in thickness. Hence the height of the slot is scaled to 4.75mm to compensate the kerf by the laser cutter, so if the thickness is different, only H1 needs to be changed.
I then proceeded to extrude everything to 5mm to simulate the thickness of the material.
The file underneath is the embedded file of my handphone stand.
So I have learned in this session how to use parametric to design models and why is it useful in actual applications in the future for prototyping. In this task, I tried out many different versions of the stand but ended up with one of the simplest ones that one can come out with as I felt that it will represent the use of parametric the best, and at the same time look very interesting. I also found it easier with the use of parametric to compensate for kerf, as instead of having to think and calculate sometimes for the thickness or the height, I can set a predetermined value and simply insert (Height-0.5) in the dimensions. I use to think that the use of the parametric is useless and an extra step, but after realizing its potential especially in complex 3D designs regarding multiple components, i will use it more in every other project in fusion 360 to come.
