This coaster depicts the logo of the Endurance mission, from the movie 'Interstellar'
NOTE: To print the lettering first load yellow, then at about 70-75% switch to blue (set the pause in your slicing software). It's a pain but it was the only way to get that fine detail on the lettering
If you don't have a 3D Printer and you want one of these coasters please send me a DM and we can arrange for me to print one for you :)
