This pinch valve allows you to control two low pressure fluids by pinching silicone hose.
Designed it so that when servo turns to 0 or 180 deg, it pinches 3mm ID 5mm OD hose enough to block flow of fluids and at the same time makes sure that servo can reach the desired position and not stall or overheat.
If you need more pinching force, it's easy to extend the slider.
K40x12 PT srews used to mount the lid on top.
Update 8.4.2024
-Quick untested model for @visarutthawo_3122432 that should work with 3/8" (9.5/10mm) silicone hose. Only step provided for this for now.
