BarBot ment for use with a weight scale.

going to use a 75 mm glass funnel and a weight scale rotary shot filling tray with clean stackable shotglasses to fill

might make a hole in the lid of the bottle like a half moon to keep it from evaporating away.

ramps 1.4 to drive the stepper motors. 60:1 gear ratio allows a mini 5 dollar stepper motor to be used.

used https://grabcad.com/library/stepper-motor-28byj-48 to make this a 10 dollar shot pouring machine

I made the holes too small on the right side so you have to use a 5/16 inch drill bit also do the gear aswell put a nut on the inside of the bottle holder and outside inbetween the housing to secure it. cut 5" and 2" peice of 5/16 thread rod and use 3 z608 bearings

fits a 26oz bottle also 2l bottle if you squish it in, going to resize it for a texas micky soon
