Freebasing 3D shapes: wine glass holder [way to go]
While the "bionic" hands are the current darlings of the hypsters, the hooks are the darlings of real people, i.e., those that actually work [definitions here / tongue in cheek / GOH DTE type stuff].
And with that, the real avenue for home improvement are the hooks.
That is where it's at, that is where the future lies, that is where the bear steps (hier steppt der Bär), that is where the pope boxes wearing a chain armour (da boxt der Papst im Kettenhemd).
"The first product was designed for a bilateral amputee who had lost his hands, but not the desire to toast special occasions with his spouse. "The prosthetic hook has a very strong grip strength, so if they were just to grab the stem of the wineglass it would probably break or be unstable," Liacouras said. Pondering the problem and staring at the hook for a while led Liacouras to an idea: Use CT to reconstruct an impression of the empty space on each side of the stem, between the prongs of the prosthetic hook, to wrap around the wineglass and hold the glass without breaking it. "This was done in 5-mm slices -- not totally ideal, but it provided the general contours," he said. "There are 3D surface scanners available, but the metal is very hard to scan and the undercuts would be extremely difficult to obtain." The wineglass holder was printed using a flexible material on an Objet500 Connex2 3D printer (Stratasys). It attaches to the hook prosthesis and includes a slot to hold the stem of the glass, he said."
