This is a remix of the Tree Silhouette Coaster by Tosh. I liked the design, but wanted something with a solid bottom to prevent "sweaty" drinks from dripping right through. I've also increased the size a bit, and added a small lip around the outer edge.
The print in the cover photo was done on a quad extruder Prusa i3 MK2 MMU as follows:
- coaster_branches_bottom.stl black ABS (extruder 1)
- coaster_branches_top.stl white ABS (extruder 2)
- coaster_branches_onepiece.stl for printing everything at once in a single colour - not used in multi-colour print
I have not tried printing this as two separate pieces and gluing them together afterwards, but it should work just fine if you choose to go that route.
When printed at 100% size, the coaster's diameter is 100mm.
