Its been a great year! This channel has gown by nearly 150,000 subscribers. Thank you to everyone who had supported Robinson Foundry. To celebrate I cast a full size YouTube play button in fine silver. I started by designing a 3d model in Fusion 360. I printed the model on my Elegoo Saturn resin 3d printer. Then I made a simple sand mold using petrobond casting sand. I melted a 1kg fine silver bar in my homemade metal melting foundry and poured it into the mold.
