One of the goals for expanding on the STEMFIE standard is to combine 3D-printable parts with non-printed commonly-available items. In this early test, a ball bearing uses standard airsoft BB ammunition measuring 6 mm in diameter.  

Stay tuned for future STEMFIE part releases containing a complete set of different ball-bearing designs. ?
