I was always fascinated by space and jealous of those, who were outside of our world. So I wanted something to have in front of me every day. So I designed simple coasters with the old NASA worm logo and printed them with Fillamentum PLA on my Ender 3 with Mosaic Palette 2. You can use any other multi-material, dual extruder or just print it as 2 separate files and then glue it in place.
Enjoy it
