Thermometer Clip for 13mm Fish Tank Thermometer

thingiverse

A simple thermometer clip for most used 13mm fish tank thermometers. The standard suction cups often lose their grip when algae start to form on the glass surfaces or when the rubber becomes brittle. A reliable alternative can be clipped securely onto 3mm or 4mm glass panes, and even thicker panes (5mm, 6mm) may be possible by bending the clip slightly. Two versions are available: one with flat edges and one with rounded ones.
