A mould that you can print out and inject silicon sealant, latex, polyurethane, etc to make your own flexible hinges for the Flexy-Hand, Flexy-Hand 2, or other applications. . Due to the new additional hinges for the Flexy-Hand 2 gauntlet attachment, I have modified this mould from the original 2 half design. http://www.gyrobot.co.uk http://www.facebook.com/gyrobotukPrint as many moulds off as you wish. For each Flexy-Hand you will need 4 of the tallest hinges and 11 of the middle height. And for the Flexy-Hand 2, you will need 2 of the lowest hinges for the gauntlet attachment. Place tape over the lower surface to stop sealant leaking. Tip : To help reduce adhesion of the sealant to the mould, a few techniques could be used : Dust lightly with talc/chalk or lightly coat with oil, butter etc.
