First test print of the 6-ball trough for #smallPinball, and I'm pretty happy with how it turned out. It prints in one piece without supports. The purpose of this first test is to check how the balls behave in it and to see if the smallest coil I have is enough to push a ball out. If not, it can be easily redesigned for a beefier coil.

The holes on the side are for mounting a circuit board that will optically detect which positions have balls in them – standard stuff.
