What is tetros
So tetros is the awesome fusion of minimalism and multi utility. It is basically a toy for acupuncture of your palm, you can also use it as an fidget toy, a piece of decoration, it can also be used for building other geometric shapes such as an icosahedron, a duck maybe a cats face and much much more.
A full design process was followed before designing the final product i.e. TETROS. You can use it for acupuncture as well as for fidgeting while reading books, watching t.v. and while working on laptops. Its dimensions are ergonomic and properly fits in the palm irrespective of different age or gender of the user. And you also know that magnets increases, rather improves blood circulation( because our blood contains iron).
It comes with customizable color scheme, hence color it according to your own aesthetics. The color scheme i have used is pastel color scheme.
Step 1: Things You Will Need!
Disclaimer- I am a university student, so all the equipment's i have used are rented and none are owned by me. You can do the same or you can find most of the equipment easily in some hardware and online shops.
1. HIPS( high impact polystyrene sheets) - 2 mm
3. Black pen
4. Pen or pencil compass
5. Neodymium magnets
6. Cutting machine or tool- ( i have used the cutter, you can use some other device for cutting the hips like the band saw or jig saw machine or a plastic cutter).
7. Flex kwik.
Step 2: Procedure.
1.Measure 3 cm in compass and draw four equilateral triangle using the same measurements on the HIPS sheet.
2.Cut the individual triangles using the plastic sheet cutter or any other machine of your preference( cut them as accurate as possible ).
3.Use the dremel to sand the edges of the individual triangles( around 0.2 mm ).
4.Now take 3 triangles and join them in an tetrahedron order, with one side open(join using flex kwik or any other strong plastic adhesive).
5. Put the magnets inside then seal the fourth side with another triangle, and join it using the same adhesive.
6.Now use the dremel again, and round off the edges and corners of the tetrahedron to the given radius's( for reference see the analytical/ orthographic drawing ).
7. YOUR TETROS IS READY!!
8.Follow the same procedure to make as many TETROS as you want. Enjoy.
Step 3: CAUTION
STRICTLY NOT FOR CHILDREN UNDER 3 YEARS OLD.
