Step 59: Chapter 8- Recycling Your Silicone
If you did in fact finish this build then you must know how expensive silicone can get. Recycle it. It will save you a ton of money in the future. Invest in an electric meat grinder (because grinding silicone by hand really sucks) and use it to grind down your scrap. You'll need to cut it up first with scissors or a knife so it won't jam your grinder. You can mix the ground up rubber into the liquid silicone of another mix. This is a great and cheap way to add volume to your molds.
