Makita "M" as coaster

I've made it in two versions.

- Makita-Coaster_flat with multiple objects, you can print it face side down and change the color via MMU. - Makita-Coaster_punched with punched logo inside, you can change the color after a certain layer. Remember that the “M” is a part of the logo it's trademarked by Makita, so I must advise not to use it for commercial purposes.
