This is targeted squarely at companies: you'll need to get in touch if you intend to copy my design to sell. For individuals reading this, making one for yourself (or a couple of friends) is fine of course, and encouraged! I just want to let companies know that they can't steal my design for profit without prior arrangement... it's happened before 😄 OFFICIAL LINKS: Support me on Patreon: https://www.patreon.com/DIYPerks/ Official Website: https://www.diyperks.com/ Discord: https://diyperks.com/discord-server/ Forums: https://diyperks.com/community/ Twitter: https://twitter.com/DIYPerks
