Tensegrity Table

thingiverse

This is an original design, using the Tensegrity concept. It employs metal beaded chain as the support and stability elements, and is designed to support a round glass top. Features at the top and bottom of the model perform dual functions; acting as the feet/glass support, while also acting as the clamps to set the length of the support chains. These endpoints have the chain pattern embedded in them, and are friction-fit for initial adjustment. After adjustment they are locked into place by M3 x 8 threadforming screws. This design is scaled to employ #6 and #10 stainless steel chain from the Ball Chain Manufacturing Company. The #10 center chain is rated to 100 pounds. The model shown is printed in PET-G, with 30% infill. This, along with the strength of the stainless steel chains, allows a fairly significant amount of tension to be used, resulting in very good dampening. The tripod base allows good stability on irregular surfaces. The clamp/feet elements angle down slightly. This compensates for any warping that may occur during printing of the larger pieces. 3/8" OD rubber bumpers are used on the 3 bottom endpoints as feet, and on the three top endpoints for cushioning the glass and holding it in position. Future improvements will include moving the hardware on the top endpoints to the underside, so they are not visible.
