About this 3D model
This is my egg stand design. It is symetrical, so you can turn it upside down. There are two stl files with custom supports. One with gap of 0,1mm to the support and the second with gap 0,2 mm. 0,1mm works for me fine. You can try to print it without these custom supports by removing them in the slicer. Even PLA can handle the "heat" in this case.
