Using Polycam to scan my model, and then using Blender to clean up and close the manifold. I then use a free software Ultimaker Cura to slice the exported .stl file, and savie it as makerbot, as I want to send it to the Makerbot Replicator+ in Makerspace in Hayden library.
I also made a feal setting for it, like have tree shapes as the support, and rotate it in a flat surface for better surface area, for better successful printing rate.
