Silicone used for grippers:
The mixing ratio is 12 grams of part A and part B and 2 grams of deadner 12:2:12
Vacuum degassing is required.
STL files for molds can be downloaded below.
I am releasing these files so that anyone who has the desire to make their own or for others ( and subsequently charge for them) can do so. Honestly, it would take some pressure off of me!
