The longest print I have made to date!  This is a 115-hour print of a 4th order Menger Sponge 122mm on a side.  Printed on an Anet A6 3D printer using Rigid.Ink white PLA.

I’m not sure if I will go for a longer print time than this again, it was a pretty nerve-wracking experience, particularly once it exceeded the 100-hours.
