Description
This is a small part I designed to pair with my dosing pump setup.
It’s a simple clip that holds the tubing against a 6 mm thick tank, and I’ve included the STEP file so you can easily adjust it for other glass thicknesses if needed.
Tubing used:
Silicone Food-Grade Tubing, 3 mm ID × 5 mm OD (1 mm wall)

I’ve added a second version that angles the tubing away from the glass.
Over time, I noticed nutrient liquid being drawn up between the tube and the tank wall via capillary action, which would then dry and crystallise.
The revised angled version prevents this from happening. 😊
