7/18/14 Modular Hand Additions

After posting our video about the modular hand last night, we received feedback about how to easily replace the strings.  We thought of this roadblock a while ago, but we decided it was time to confront the problem.  We decided to use the same snap fittings to be able to move the entire 'tuning block' from hand to hand.  Here's a prototype we drew up and are in the process of printing.

Here's the piece we printed today.

This part houses the tensioners.  The rectangles act as the female part of the link.  The male parts come out of the gauntlet.  This set up will keep the fitting from going inside the gauntlet and interfering with the wearers arm underneath.

The mid gauntlet finished printing today as well.  However, the female half of  the fitting is slightly to small for the male half.  And the walls of it are too thin.  With some tweaking, the mid gauntlet should be ready to go.

Someone mentioned the durability of these fittings.  Right now we are printing the prototypes in ABS, however, the male part isn't as flexible as we hoped.  To overcome this, we plan on printing in nylon to get more flexibility and durability.

That's all we have for today.  Join us next week when we finish the Modular Hand and maybe start another project!
