Scale At Given Print Units
200x for peptide chains, 160x for heme molecules as surface, 200x hem molecules as balls and sticks
Pre- and Postprocessing Instructions
The model was re-orientated in Cura so that the opening for the hem binding pocket will be upwards. This way, the amount of support inside the binding pocket was minimum. Nevertheless, some support was built inside the pocket but it was easy to remove. Gcode for chain A, B, and C have the hem molecule at 180x, 170x and 160x and will not fit the binding pocket. Gcode for chain D has the hem scaled at 140% and will fit the pocket. Printed at 0.2 resolution with wall 3 lines. I have used concentric supports and found to be easier to remove. The support removal was a bit tricky for the hem as balls and sticks.
