Final project
1.CAT POD
A resting space for cats which can be closed using a phone whenever the cat parent wishes to.
2.AUTOMATIC LOUVER
I have always liked the concept of lovers and I have been fascinated by some of their designs too. One thing that I have always thought about is how to make them more efficient. Hence the idea of louvers that will automatically adjust their angle according the direction of wind.
3.Bloom
Introduction
The project is basically a blooming light which will give the impression that it glows when the flower blooms.

Design File
Evolution of design
- Design of pattern
The design was shown in the video I referred to but I still I had to figure out the pattern which enables proper movement
I tried cutting the pattern of with slight changes in dimension. As of now the pattern works in a chart paper. I have to figure out what material I can actually use.
Factors to be considered while choosing the material
- Has to be stiff enough to maintain the shape after creasing
- Should let light pass through it
- Should’nt tear or wrinkle after using multiple times
Working
Cutting in Zund
CNC cutting base
To see if the design actualy works, it was important to cut the base so that the other part can be assembled on it. So I decided cut the base as soon as I finalised the pattern
3D printing parts
I have finished 3D printeing almost all the required parts. Mainly shafts, clamps, gears
Lase cutting acrylic rod
The design I refered actually used a MS rod but I decided to use acrylic board instead. I was also doubtful about the length of the rod until I finalised the pattern. The length of rod controls how much the pattern can actually bloom
Progress as of now
