Summary

This gadget is there to clean clogged pipes with water pressure. It consists of three parts to be printed - two sealing rings made of TPU and a cone made of any hard plastic. I recommend buying a stop valve to turn on/off the water jet. A garden hose must be connected for the water supply.
Important: all other openings between the drain and the blockage must be closed so that the water does not escape there but instead exerts pressure on the blockage.

In my kitchen this works better and easier than all the household tricks, chemicals or drain spirals i know.

Drain diameter max.: 5 cm (2.1 inch)

small O-ring: Resolution 0.05 mm, no supports
cone sealing ring: Resolution 0.10 mm, supports yes
cone: Resolution 0.15 mm, supports yes
