So at work I am baffled by a problem to bend a flat plate (3mm thick max) using string where the string is encased in the plate. So naturally I 3d printed some plates and attached a string but found as suspected that the plate would only bend when the string had some angle > than a few degrees getting progressively easier to bend approaching normal. This led me to researching how other similar designs accomplish this and ultimately my question. I have seen many pictures but not a very good write up on how the fingers bend in the 3D printed prosthetic, when the string bending them is parallel with the surface. It appears that most of the designs do it this way so the strings aren't all over the place which makes sense. The only way that I can think of is that the fingers are already bent and the string pulls them erect but it appears to work the opposite. So if anyone could shed some light on this I would be grateful.
