G1 to 25mm Karcher BP3 pump pipe adapter

I added a 30mm o-ring at the end of the thread on the original design.

This is now a good copy of karcher's system like on the BP3 pumps.

The photo illustrate the male to male karcher's adapter... it fits both input and output of the pump. G1 threads (1")

I suggest printing in PET or ABS with a 100% infill for the best 'waterproofing'.

Maybe screw and unscrew a few times on a metal female to clean it a little before plugging it in the pump.
