Used bed temp of 70 deg Celcius, after 5 layers bringing bed temp to 60 degrees by lowering it 1 degree every 2 layers. This was done to get a good sticking first few layers and prevent warping due to high bed temp. Had to edit the gcode for this after slicing. Built-in supports came of very easy and after a few tries the wrench moved a bit smoother. Very nice design, well done!
