Tessellating Flower Coaster Reloaded

This is a re-design of my tesselating flower coaster. Whilst I had originally been happy to use filament swap as a means to change colours, I found this method to be unpredictable when changing from PLA to ABS (the ABS petals ocassionally failing to adhere) and the flowers are limited to one colour only. A re-think was in order and I decided an inlay method would be the best way to go. Not only would it give me the freedom to have as many different coloured petals as I would like, there was the challenge of creating two models which must fit together and appear seamless. I used this software to design the tessellation with: http://www.peda.com/tess/
