terrence howard curved tetrahedron (tree supports)

i replicated terrence howard curved tetrahedron that was recent shown in JRE, is the negative volume obtained from the mapping of 4 partially overlapping spheres. the step file is scaled 300x and rotated to seat on the bed, supports are requied as the three vetrices are essentially singularities (i.e. 0 thickness vertices). enjoy. i am looking at create a lynch-pin drone next to see how it flies.

an interesting experiment would be generate a conductive version of this geometry (i.e. make it from metal) and prescribe 4 electric fields (at the center of each of the curved faces) and 4 magnetic fields (aligned with the vertices), making sure that the angle of incidence is 120 degrees just as he talked about in JRE.

i used: nozzle 0.4mm, PLA Basic, 0.2mm Layer height. generated on P1S
