Printed at 0.2 resolution with 2 wall lines and 5% infill. Extensive supports are required but were rather easy to remove. The amylopectin was reconstructed using the 30 residues amylopectin and amylose atomic coordinated available on Proteopedia (https://proteopedia.org/wiki/index.php/Carbohydrates_II) . The amylose was re-heated afterwards with a hotgun, and slightly reshaped in order to fit in the amylase catalytic site. Once the right bend was achieved, the amylose piece stuck to the amylopectin piece by simply re-melting the two ends and fusing them together.
