I went through a few print providers and found Printify's default sticker printer to be really good. Much better quality than I had been getting out of the Redbubble or Teepublic printing. And yes, each logo is actually a composite of 24 triangles that makes a mosaic that resembles the logo. It was fun to make them and then squint and be like, yeah, that does look like the Debian swirl. After I finished my laptop I kept making new ones and put them up for sale. If there's any project you think I should do next, let me know.
