Exquisite Corpse Chair 01
by OpenDesign, published
This chair was created using the Exquisite Corpse method of designing, concealing and passing it on to the next player for their contribution.
Each player was only given the top slice of the previous design to work from. Their design had to utilize digital fabrication and the design files had to be open.
The three players were Ronen Kadushin, Jens Dyvik and Nick Graham. Designed from the bottom up, the chair was split into three parts. Legs, seat and back.
This is the result.
For seatBack file:
CNC cut from 18mm timber/ply.
For bracket3mmMildSteel file:
Get files laser cut from 3mm mild steel. You could go thinner. 3mm was just insurance that everything was going to remain in the same place. Once cut, fold the 4 longest folds first. Make sure that both brackets are mirrors of each other and not copies. Then fold the remaining folds away from the center of the bracket. Note each fold should be 90 degrees. Attach to the seat frame using an M10 x 90mm bolt and nut for each bracket. See images for reference.
For seatPan12mmWood, seatFrame25mmWood, seatText3mmAcrylic files:
The CNC millied parts should be made from massive wood planks 25mm and 12mm thick, minimum width is 80mm and 100mm (see reference file). The dogbones are designed for a 6mm milling bit. The engraved text for the seat planks should be milled with a 6mm bit and 3mm deep. The depth of the different pockets are specified in the layer names.
You should be able to import the dxf directly to partworks with color coded named layers. Remember to join open vectors once you have imported.
The lasercut parts should be made from 3mm thick pink, purple or similar acrylic.
To assemble the seat to the legs you will need 8 x M10 90mm long bolts, plus nuts. There is 0mm tolerance on all the parts. I recommend a sharp single or doubleflute upcut milling bit.
For legsOak file:
Machine out of oak, on a CNC. These chair legs were inspired by designer Phil Cuttance and his faceture project.
