Simons Cat hungry fridge magnet

Cute Simon's cat fridge magnet. 

Use 10 x 2 mm round magnets or 20 x 10 x 2 mm rectangular magnets. 

Add a color change at 3.2mm to get the outline black.

By request I uploaded a version for 12 x 3 mm Magnets.

If you have problems with the black outline, try to set a different width for perimeters and external perimeters. I used 0.4 or 0.36mm on the 0.4mm nozzle.

Or use the Arachne perimeter generator in prusa slicer 2.5.0 alpha.

Check the preview in slicer until you like the result.
