The file 'Coaster Für Children With The Letter “M” 3D Printer Model' is (stl) file type, size is 8.8KB.
A coaster for kids who are fond of the letter "M" (for example if their names are something like "Mia" or "Mike"). I designed this in a diameter of 7 cm - for the regular size of 10 cm, simply adjust it in your slicer.
