I've been trying to think of a good efficient way to cast hoses, something to connect to a gasmask. We are talking 28mm scale. I've considered a semi-rigid resin but I fear that may not be flexible enough. I have also heard mention of actually using silicone to cast with, in place of a resin.
My plan is to cast them with a thin wire in the middle to hold shape when it's bent. Any experience or ideas on how to achieve such a result?
