Paddle tires for 21x12 rim-silicone molds

thingiverse

These are silicone molds for a power craze 1/32 or any other car with a 21x12mm rim. Tires may have trouble getting out when you separate the 2 pieces. In order to make the mold, you need low viscosity liquid silicone. Place the 2 pieces together. It shouldn't matter how they go together but it might. I have not tested these but I will soon enough. Pour the liquid silicone into the funnel at the bottom of each piece. Wait for the curing time of your chosen silicone type, and separate the 2 pieces. If you are unable to get the tires out without damaging them then you should just break them with a hammer. The tire will resist that as it is flexible. You need low viscosity silicone because the funnel hole is very small. When it's done curing and you get it out, cut off the scraps.
