This are two moulds to make all hinges needed for a flexi-hand at one time.


The mould is printed with PLA, a layerhigh of 0,2 mm and a fill density of 20%.
To cast the hinges I used a 2-K-Silikon named "Wacker Elastosil M 4370" whitch I had in stock.
But I think a lot of other Materials will work also.
For all hinges you need about 16 ml.

To get the hinges easy out of the mould I also designed to smal parts to press them out. This works realy fine.

But the Material I used was not the best choise. So my second try was with dragon skin 30 and this works fine!
