Thermometer holder

Spring-clip for mounting a standard laboratory thermometer on a wall. I use this to mount thermometers near temperature-sensitive laboratory apparatus in undergraduate physics labs.

When 3D printing this, make sure that it is upright on the print bed so that the "grain" of the print is perpendicular to the thermometer. If the grain goes in the same direction as the thermometer, then the spring-clips just break rather than holding the thermometer firmly.
