Thermometer Magnetic holster

After covid I design a Magnetic holster for keep this cheap Thermometer near to refrigerator, ugly but functional you must add 2x 8-9mm neodimium magnets, it support AAA batteries loaded inside but results in this hanging angle. Since it is made as a boolean of a scan fits very accurately, but due to the roughness of the scan fit, but it may require some minimal sanding or resizing to less than 1%. 3mf its already scaled .5%+.
