Aquarium filter support

I installed an internal fish tank filter. The little ones that stay on the corner inside the aquarium and fixed in position with suckers.
It was always a pain to remove the filter in order to clean it with those suckers, so I decided to create a support that holds the whole filter.
Now I can easily slide up the filter.
The filter is a Jeneca GBL-800

I've used PET-G for this print. Print on the side without supports
