Week 3

This week, I designed a mouse.

Explain for my product, my final project is wireless silent wooden mouse.
So I had to design a mouse, But I wanted to use the easiest tool because I was the first to use design tools.
And I thought how to design it to be comfortable, beautiful and efficient, and it was very difficult in that sense.
I thought about the shape of the mouse and how I would put things I wanted, and I decided to make a mouse as I sketched in the paper.
I have used Inkscape, Mypaint for 2D work, and FreeCAD, Fusion360 for 3D work.
First, 2D sketch.

Inkscape.

Mypaint.

It is a 2D sketch drawn from an inkscape. I've never used a program as simple as it.
Inkscape is a vector-based program.

It is a 2D sketch drawn from a mypaint. It is similar to mspaint, but it has a little more functions. Depending on the user, it may appear to be hand-drawn.
Mypaint is a raster-based program.

It shows the difference between vector-based and raster-based.
vector-based does not show the pixels even when zoomed in. So It is neat when you modify it without breaking it even if it is deformed freely.
But, raster-based shows pixels when zoomed in. So it isn't confortable when you modify.
To explain the difference of the inkscape and mypaint, Inkscape is a simple tool. You can do many things with one tool. And mypaint has a lot of tools so you can work in detail.

Next 3D work. I used FreeCAD.

But, sometimes it doesn't work in my computer while I working.
I found some solution, but unfortunately there was no solution. I think my computer performance is bad, so it sometimes stopped.
So I changed program to Fusion 360.

I think it's powerful but lighter than FreeCAD.
Let's start to make a mouse.

I started with draw a cube. Using extrude in the top bar, make a new body.

Using extrude in the top bar,

Cut the basic mouse shape,

Using revolve on create tab of the top bar,

Cut like this.

Personally, I don't like the square end, so I trimmed it using the cut function.

I painted a circle using the y-axis and then used the extrude function to create the wheel.
And let's change the material.

Right click in the empty space, click Appearance.

You can show this windows. Choose what you want. I choose mahogany.
After choose the material, click and drag to the product.

Wheel is made of rubber.

This is a capture for each part. 3D part is finished
