Hose Clamp

I designed this to clamp off the hoses on my milking machine.

The hoses are silicon 19mm OD and 3.5 wall thickness so the clamp squeezes down to 7mm when fully clamped.
Easy one handed operation seals the hose completely.
Use 3 x 40mm socket heads to bolt it together over the hose.

I printed them in PLA because that is what was in my printer at the time, and I am too lazy to change but maybe PETG would be the best.
