This is a set of 19 different coasters & holder displaying ESA's interplanetary spacecraft JUICE (JUpiter ICy moons Explorer), the moons it will visit, Ganymede, Europa, and Callisto, their host planet Jupiter, and bonus, our moon ("Selene"). Each is also available in several forms on their own for your own projects.

Coaster dimensions: 100 mm DIA x 6 mm tall Designed with usability in mind - your cups will stay level.

My Print Settings Printer: Ender 3 S1 (base) Slicer: Cura 3D Layer Height: 0.12 mm (fine detail) Ironing: ON, Zig Zag (Turn off for COASTER-HOLDER) Walls: 2 (works well with ironing for edge detail) Top/Bottom: 5 Infill: 80% (100% preferred) Infill Pattern: Zig Zag Adhesion: Brim (& glue stick)

Time @ 60 mm/s: 5:45 (6:30 for bottom text; 8:00 for HOLDER) Filaments: OVERTURE Rock White PLA; Polymaker Matte Charcoal Black PLA

Finish Add some hand painting for fun! Text on bottom will need painting.

Design Platform: Blender Process: Real images (detailed below) were traced by extruding vertices from a starting circle. Sectioned up, given thickness, and then much trial & error and many complete redoes. Blender file will be provided if possible.

Descriptive texts on coasters were collected from ESA's website, the JUICE mission Wikipedia, or each moon's Wikipedia.

NOTE: If you are having trouble printing the text on the bottom or want to remove it, it should be easy flatten or cover up in a program like blender or Tinker CAD (or complain to me I suppose).
