Camper van cheap water dispenser solution

I made this model to attach a water dispenser I bought on Amazon to the countertop of my camper van's kitchen furniture.

It was made to be screw with 4 regular wood screws (4mm) using the 3 side holes. The center hole is made to let the hose go through the countertop.

It's a pressure fit, the TPU will compress a bit and make a tight fit.

Print in TPU 15 or 20% infill

UPDATE after almost 2 years of use:
Still sturdy and grip the water dispenser quite tightly.
I faced quiet a lot of weathers, humidity and temperatures and nothing move
