Stool-T is constructed of many blocks, which are bound by small parts, and can be re-constructed into other patterns, similar to playing "Tetris". Each block shape is the same as the seven seen in "Tetris": I shape, J shape, L shape, O shape, S shape, Z shape, and T shape.

This was designed as an entry for the Tenkaizu Budokai stool contest:

- base materials: maximum of 2 sheets of MDF t2.5mm - 1820 × 910mm can be used (according to contest rules)

- tools: laser cutting machine (trotec speedy 300)

- software:

blocks / Rhinoceros + Grasshopper > Illustrator

binding parts / Rhinoceros > Illustrator

Because of the limitation for base materials, the unit size for blocks is set as 4cm.

It is scalable via Grasshopper parameters. Bigger and/or more blocks shall be much more interesting.

One base material is cut into four max-work-size sheets (730 x 437mm) and one sheet of 730 x 179mm, referred to as a "hazaiA sheet".

For this stool, the following number of sheets are cut according to the attached drawings.

stool-T_A.pdf ; 4 max-work-size sheets

stool-T_B.pdf ; 2 max-work-size sheets

stool-T_C.pdf ; 1 max-work-size sheet

stool-T_hazaiA1.pdf ; 1 hazaiA sheet

stool-T_hazaiA2.pdf ; 1 hazaiA sheet

The following are optional parts. They are used for the backside cover if you want to store any remaining blocks inside the stool.

#4: overlocking parts of #1 under top surface blocks

Step 3: Construct Side Walls

construct four side walls with binding parts #2 and #3.

Step 4: Construct Two Walls

construct two walls with binding parts #2 and #3.

Step 5: Construct Third Wall

Before constructing third wall, binding parts #1 are inserted into the holes of top blocks, then construct third wall.

Step 6: Complet Side Wall and Top
