18.5 hours.
Practically full size stanford bunny - ie: the size of a real (smallish) bunny.
At the time I did nor realise that if you went to a custom profile in makerware it reset all existing settings.
So instead of a hollow bunny at 0.4 mm layer height (wanted to see how quick I could print one), it printed 20% infill at 0.1mm layer height.
So I just let it lol
