After my apartment got flooded I devised this simple clamp so it never happens again.
It can be adjusted for any small pipe or hose push-fitted connections using Oneshape:
d - smaller diameter
D - bigger diameter
max - maximum diameter (of the ridge/lip)
h - summed height of the ridges/lips
Any print settings should do, it has quite lose tolerances. I printed with 0.2 layer, 150% speed. No supports required.
The attached model fitting:
d = 25mm
D = 36mm
h = 17mm
max = 42mm
The author marked this model as their own original creation.
