Design 1

Idea

I'm planning on creating a stool for my first design. I need a stool in my room. Sometimes I need to get something from the top section of my bookshelf. I don't want to use my normal chair since it has wheels, which means that it's dangerous to stand on it. Also, sometimes, I want something to rest my legs on, which is why I want a stool.

Design Process

First, I created some parameters.

I sketched the first part of a leg. I want the stool to have plus shaped leg base. The middle has the equation material thickness / 2 + 2 * clearance.

I extruded it according to the material thickness.

I created another one that'll fit that piece.

I added don bone fillets with the tool diameter parameter.

I went back to the design of the second body and added a 350mm by 40 mm rectangle to increase the height of the stool.

I added another part to connect to the top part of the stool.

I added the dog bone fillet to the new part, too.

I created the top of the stool with 4 slots to input the legs. I used the three parameters while creating it.

I added dog bone fillets to it.

This is how the stool will look like.

Idea

I want to design something that can hold my computer, some plates etc. while I'm in bed, on my couch etc. Kind of like a portable table. I'll use Cuttle for this design.

Final Version

Design Process

I created two parameters: clearance and tool diameter, which have the values 0.3mm and 6mm, respectively.

After measuring the width of both my legs together, created a few more parameters.

I later created a material thickness parameter, which has a value of 2cm.

I divided the thing to two components: top and sides.

I created a rectangle with width width and length height.

I created a rectangle to use as a connection part to the sides component. You can see the parameters I used at the right part of my screen. I made it so that the hole will always be 1cm away from the left and the top of the big rectangle.

Then, I did this for the other corners, too.

I realized that I forgot to add dog bone fillets and some clearance, so I added those. Here, you can see them scale:

I created two rectangles to use as guides. One with the width width, and the other with the width width/2. The top two rectangles are for the connection to the top component.

I used the pen on the parts.

I implemented the parameters. I also added a dog bone fillet to required locations.
