Aquarium glass clip for airline tubing
Airline and CO2 tubing float loose in an aquarium and kink over the rim. A glass clip straddles a 6 to 10 mm tank wall with a U-shaped body, holds two 4 mm airline tubes in 4.2 mm channels with a 3.5 mm snap opening, and has 1.5 mm walls so it does not shadow the tank. Printing it flat in PETG keeps it waterproof and inert, and a 0.3 mm draft on the rim slot lets it slide on without scratching the glass.
Tank walls vary from 4 mm nano tanks to 12 mm rimless ones, and SpeakCAD generates a clip to your exact glass thickness and tube diameter. Ask for a third channel or a heater cable slot in the chat, then preview free in the browser.
Design an aquarium rim clip with a U-shaped body for 8 mm glass, 1.5 mm walls and 25 mm depth, two snap channels 4.2 mm diameter with 3.5 mm openings on the outer face, 0.3 mm draft on the glass slot, and 0.5 mm rounded edges.
