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.ai ; 4 max-work-size sheets
stool-T_B.ai ; 2 max-work-size sheets
stool-T_C.ai ; 1 max-work-size sheet
stool-T_hazaiA12.ai ; two patterns are cut with hazaiA sheets

The following are optional parts. They are used for the backside cover if you want to store any remaining blocks inside the stool.
stool-T_A_waku.ai ; 1 remaining material of stool-T_A.ai
stool-T_C_waku.ai ; 1 remaining material of stool-T_C.ai

The parts list is attached just as a reminder for myself (Japanese only): "stool-T_PartsList_0926.pdf"

Assembling steps
Step 1: lasercut parts of blocks and binding parts
Cut MDF sheets for seven shapes of block.
Also, cut four kind of binding parts.
' #1: long parts, supporting member under top surface blocks of Stool.
' #2: long parts, binding member of side wall blocks
' #3: overlocking parts of #2 on side walls blocks
' #4: overlocking parts of #1 under top surface blocks

Step 2: assemble blocks
assemble 63 blocks

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

Step 4: construct two walls
construct two walls assembled on Step3 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
construct fourth wall to complete side wall.
top blocks are bound with the binding parts #4.
Now, Stool-T is completed !

Step 7: optional assembling
Bottom cover is optional. They are used for the backside cover if you want to store any remaining blocks inside the stool.
Two bottom covers are inserted between binding parts #2 and #3.
