Duplicating Parts Using Silicone Molds

A walkthrough of duplicating small plastic parts using silicone molds and resin casting. The process involves building a simple vessel from craft supplies, pouring silicone around original parts to create negative molds, then repeatedly filling those molds with resin to produce accurate duplicates. The guide covers the basics for simple geometry and briefly notes that more complex parts require advanced techniques like degassing.
