SpaceX Coaster

This is a coaster with the SpaceX design. Very simple, with an ~1mm lip, to keep your cup from sliding off.

I've found that 3D printed coasters have a tendency to slide around a lot, so I put some 3/8" bumpers on the bottom (I use 6 of them for stability) that I got from Amazon. (http://amzn.to/2qy3L5o - I have no affiliation with that company, but those are the ones I use)

These work very well printing at 0.2mm, with a color change if you can do that.

I'd recommend a more striking Blue
