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.

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

Step 1: Assemble Blocks

assemble 63 blocks

Step 2: Cut Binding Parts

many many binding parts are cut also.

#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 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

construct fourth wall to complete side wall.

top blocks are bound with the binding parts #4.

Now, Stool 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.

<p>Whoa! This is really impressive. Very cool stool!</p>
Wao! So prompt comment for my first project using laser cutter.<br>Thanks to cool tool Grasshopper.
