A cool and simple coaster of Freddie Mercury. It uses a simple manual filament change. The coaster is 17 standard Bambu lab layers thick (0,2mm), the image is 2 layers thick, so simply insert a pause at 15 layers to change the filament color.

The coaster belongs to a series of 6 coasters that were designed for a custom order, I thought I'd upload them here in case anyone likes them. See the other coasters on the second image.
