snack dispensing machine concept (for Lab424, Twitch)
using:
mason jars with metal lids(no center piece)
3d printed jar holders
3d printed "X" turning pieces(1 per jar)
3d printed opposing side turning piece(1)

spacer/roller-bearings for jar holders(2 per jar)

stepper motors(3)
stepper motor shaft adaptor(3)
stepper motor shaft(3)
stepper motor shaft to solid mount(1)

servo(1)
servo arm(2)

guide rails(4)
light break sensor(1 for each stepper motor to determine home pos, although a tactile or trip switch would work just fine if using stepper motor in one direction to achieve end location)
pillow bearings for main food wheel(2)
"retaining" zip-ties (one per bearing, used on outside edge to keep from shaft walking out of position)
and finally:

an Arduino (probably a mega at this point...)
and lots of code to make things move properly...
