Material

These are designed to print in PLA by default - it's easy to work with and available in a huge range of colors, which is great for matching realistic cartridge appearances or color-coding calibers.

If you plan to use these as functional snap caps in a real firearm, consider printing in PETG instead. It's a stronger, more durable material that will better hold up to repeated use.

Let me know if you'd like any other calibers. I'm happy to model them.
