Servo Ball Valve, 1/2" Drip Irrigation Tubing

Use MG996/995 Servo to control on/off ball valve used for 1/2 inch drip irrigation tubing or other water line.

I used this valve https://www.amazon.com/dp/B0CQXKJ26B

Need hose clamp to prevent leakage. 

Tested with MG996 servo. https://www.amazon.com/dp/B09LS7RB5J

Trim ends of dual servo horn for insertion/attachment to small gear. 

A 180 degree sweep gives a ¼  valve rotation. Power was about 250 ma at 5V when turning. 

Printed with PLA and PETG, 0.16mm layer height. 

Need M3x20 mm bolts.

Glued valve knob to large gear for added stability.  Used Cyanoacrylate
