We have a new obsession: printing calibration butterflies on our INDX. Otto the calibration butterfly is the model we recommend starting with. As the name suggests, we designed this model to verify that your printer is properly calibrated after assembly, while leaving you with a cool first print you can show off. 🦋 printables.com/model/1761475-otto-the-calibration-butterfly
