servo actuated valve controller

This is a very useful servo accessory that I have made to remotely actuate panel-mounted fuel valves. Designed to fit most 1/4 in compression needle valves, this adapter interfaces these valves with a servo motor so I don't have to be close to my rocket engine test stand if things go horribly wrong. It is supposed to use a 25kg-cm servo motor with 270 degrees of rotation in order to have enough torque to fully open and close the valve. This adapter can be used with remote control or Arduino to remotely control the flow rate of any type of fluid. It can also be used with ball valves if the "valve_turner" part is slightly modified. From automation to remote control vehicles, being able to remotely control fluid flow rates can be extremely useful.

Printing:
the two parts of this assembly will be subject to very high torques when the valve is being turned so use a strong and rigid material with 100% infill. use support on both parts and a brim if adhesion is an issue.
