Fridge Toys: Atla Earth Symbol

The model is meant for 2 color printing with a single extruder, you change the filament at a certain height. The base has 4 mm and then the drawing follows with 0,3 mm. 

Slice it with a layer height of 0,3 mm.

and in the slicer insert a “Change filament” before the 15th layer (check the preview where the drawing on top starts!) and thus you can print it black on white or what colors you prefer.

The magnet goes into a hole on the back, it's made for 8mm diameter, 2mm height neodym magnets. The hole may need some sharpening of the edge after print and should hold the magnet tight without glue.

Print it with (tree-) support for the magnet-hole.

Going down with feed rate and temperature for the last  layers may help avoiding stringing.
