coffee machine water tank refiller for lazy people

My coffee machine is kind of hard-to-reach, so I needed an easy way to refill the tank without pulling it off and back in every time.
Basically, its a 3d printed funnel with attached 5mm (inner diameter) tube.
The other end of the tube is connected to the water tank, so you might need to drill small hole into the tank.

I also added a second model for standard 4mm aquarium tubes, but i did not test it.

make it waterproof

I covered the inside and outside of the funnel with aquarium-safe epoxy resin.
Use icetea (or at least cold tea) or any other colored drinkable liquid to see if your print is waterproof. Attach the tube and hold the other end above the funnel, so liquid would stay inside funnel, put some liquid in.

if you want, you can copy and adjust the model for your needs:
