Aquarium, tank dosing tube holder

I have designed a "Dosing Tube Holder" that perfectly fits aquariums with a 4mm glass thickness.

The holder is designed to prevent capillary water overflow, even at high water levels.

I printed it using PLA, but I recommend PETG as a better solution due to its superior durability and water resistance. No supports are required for printing. All other parameters can be adjusted at your discretion.
