Week 2

 Welcome back, for this week, I have been assigned to do a 3D model of a handphone stand. So first I had to measure the height, length and width of my handphone. The measurements are approximately 160mm by 73mm by 8mm. Next I decided to have a traditional curved handphone stand where the stand is just a curve and there is a protrusion near the bottom of the curve to hold up the phone. So first I decided on 150mm between the 2 points of contact on the table. 

    Next I used the conic curve sketch to create a curve from the 2 points with a height of 200mm. I used 200mm to give a bit of redundancy to the height of the phone and allow for a larger variety of phones to be able to be supported by the handphone stand. To achieve a height of 200mm, I first created a conic curve with a height of 260mm but with a rho value of 0.75. I then deleted the 150mm line as it was only a reference point, and drew one line on each of the curves with a length of 25mm. This would be the thickness of the stand.

    From the 25mm protrusion, I plotted another conic curve with a height of 280mm and a rho of 0.75. Now in between the curves is the target height of 200mm. 

    

    Now to create the protrusion where the phone would be supported, I first need to draw a line with a length of 25mm from the base to create a point where I can draw the protrusion since you cannot intersect lines with curves at a point. From that point, I created a rectangle, 30mm by 10mm and another rectangle 20mm by 10mm to create a ledge to prevent the phone from slipping off.

    

        While I started the rectangle inside the curve, this means that the ledge width is not 30mm which is fine, while slightly off, the width is more than enough to accommodate a phone including its case. Finally, I extruded it by 10mm. Since the phone measured a 73mm width, 80mm is more than enough and allows for extra space for wider phones. To ensure the design is parametric, under the modify tab, I clicked modify parameters, opening the window below. 

   

        I then added in all the necessary parameters for each part of the design so each measurement can be changed easily.

    

    This is what it looks like now with all the parameters in the place of the measurements, the fx in front of the measurements confirm that the measurement is using a parameter and not a manually entered measurement.

    And there you go, all done! I have put the HTML file of the design below. Enjoy!
