Sensor Case Open End w Lid (Keyestudio)

This is a case for Keyestudio sensors/modules, 20x31 mm. This design is for sensors/modules, wich need an open end, such as collision detector (https://wiki.keyestudio.com/Ks0021_keyestudio_Collision_Sensor).
The lid has a snug fit and closes well. (The sensor/module is also with a snug fit but if you want to feel more secure you can add a small piece of dubble-sided tape on the underside of sensor/module.)
