torque limit wrenches
thingiverse
Finger tight?!?! Is that British or imperial units? What does that mean exactly? My 2-year-old can do finger tight and break some things; she's incredibly strong! These wrenches, size 1/2 and 7/16 inches, should deliver the calculated torque shown. Ten inch pounds of force is not a lot, so I think finger tight would be around this amount. Imagine applying one pound of force to one end of a ruler; the force on the other end of the ruler is twelve pounds. Physics is awesome! They are also plastic and very lightweight. NASA and U.S. Military, I'm thinking of you. Wouldn't it be great to have lightweight disposable tools in space? Yes, it would! Wouldn't it be great to reduce the amount of weight a soldier needs to carry? Yes, it would! P.S. I calculated the torque required for plastic to yield based on PLA not Nylon-based filament; this is only an estimate.
