Kart5a is 17 and from Finland. He makes lots of fun 3D printed things, such as the one handed bottle opener. He also makes videos about these things. They explain the printer settings, design changes and show how the product is made. I think this is a great way for community members to share their work and show others how to make things. The videos are in Finish but he’s added subtitles for us so we can all learn about his process. I’d love to see more videos like these!
