@Opcion3D has done it again; he released his newest STEMFIE project and member of the Star Wars family; meet Baby Joda! You can download this wonderfully cute 3D model from this link.
The STEMFIE Quick-print Sample file is an easy way to test a few STEMFIE parts and fasteners. You can also check the STEMFIE Calibration File for more elaborate types of fasteners.
Check out the STEMFIE web app prototype to browse, view, and download parts (Github).
