Printed at 2.5x scale (104.4 mm x 84.6 mm x 132.1 mm) using a Printrbot Simple Metal and the Cura software package.  Support structure included a raft and the \touching buildplate\ support structure with 20% support fill. Model infill was15%. This was a roughly 10 hour print job (~21m, 62g of material). Remaining settings were default.If you want to mimic the green luminescence​ of the protein you can insert a green LED attached to a button battery. In my case I used a 3V watch battery to power a 5mm, 2.1 V, 30mA green LED. Both can be had at Radioshack for six or seven dollars.
