This is a model I found on Cults3D and later on also on Thingiverse. So I will reference only the Thingiverse link.
The model was repaired - there was some skin problem, resized to 6" ( 155mm ), and hollowed. The wall thickness is 1.5mm. When you scale it please take care that the wall is still thick enough for your printer.
I have uploaded both the repaired file and the hollowed file.
Enjoy!
