What is Pitagora 3D?
A tool for assembling a triangular skeleton with joints and connecting rods.
Please try experimental modeling such as art design and interior design.
・"Pitagora 3D" is an epoch-making 3D structure that assembles various three-dimensional structures with different apex angles and side lengths with adjustable length rods (connecting rods with positive and reverse screws) and two types of joints. It is an experimental tool.
We recommend a 3-piece set including joints and rods, a 4-piece set, a 5-piece set, and a 6-point 4-color set. The joint has 6 arms (6J) and 5 arms (5J), and the rod has lengths of 55 mm and 83 mm. The 83mm rod is included in the 5-piece set. There are also packs with only joints and packs with only rods. (Extra pieces are weighed in each pack just in case).
The required quantity varies depending on the shape, size, and structure to be assembled.
Simple but confusing. But there is a mysterious regularity, and when you notice it, the shape expands infinitely. Please create your own structure by referring to the example photos and videos posted on the top page.
The rod can be cut arbitrarily and used, but we recommend a nipper with a sharp blade so that the threads will not be crushed. Also, when adjusting small parts, it is convenient to have a needle-nose pliers with a bent tip. (There are various 100-yen shops as well)
Pythagora 3D points and tips
(1) For Rod connection, adjust the screws evenly at both ends. For tight intervals, screw deeply into one side, insert the other end into your mouth, loosen the screw until it spins freely at both ends, and then tighten it again to make it even.
(2) You can push in up to two threads, but adjust the more with screws. When pushing it in, be careful not to pierce it with the back of the Joint or the sensation of your fingertips.
③ There is a direction of hozo in the union of Joints (especially 5 arms). If you turn it over and spread your arms, it will look like a baby sea turtle, so if you remember the position where you look at the baby's head as a mark, you can see the angle at which it can be combined well.
(4) Rod cutting is optional, but as a rough guide, if there are patterns of about 16 mm, 25 mm, 30 mm, 40 mm, and 47 mm, the size before and after that can be adjusted with screws. (The size of the golden ratio is also within this range)
Also, as a ruler to measure the cut position, it is convenient to use a bamboo ruler with a scale to the end. It would be more efficient to use one as a template and cut two at a time.
⑤ The uncut part of Rod can be used for bolts or reused in short places, so it is convenient to store it in an accessory case according to the size. (There are various plastic cases in 100-yen shops.)
(6) If the apex is an acute angle, cut the hozo protruding on the back of the joint in advance so that it does not interfere with the gathering Rods.
⑦ Above all, I think it is better to gradually build the whole picture without rushing ahead, and to balance the whole after the screwing depth etc. has reached a certain shape. The more complex the tension balance of all materials forms the structure, the more you need to balance while looking at the whole.
