Water pump adapter

This is a nice adapter for low cost water pump Sun-Sun HJ-1141.
I guess that more pumps can fit but I have tested only the above
I need it for this project https://www.thingiverse.com/thing:3405964.
It allows a simple 10mm hose to connect to the above pump to use it for hydroponics
The thread screw perfectly with no force and it adapts flawlessly
In fact you should not use force to screw it or it may breaks

I printed on PETG, Layer Height 0.4, Infill 15% and with a small raft for clear detach

I don't know if this breaks any warranty and I absolutely take no responsibility for any damage on your equipment.

I upload the FreeCAD file for anyone needs to modify it
