Humidity sensor spool bracket, Fill3D spools

When you are just simply storing your spools in a zip-lock bag and want to know the humidity inside the bag. Putting in a humidity sensor on its own can be bothersome. So I designed this sensor holder to mount the cheap generic Chinese humidity sensor in the middle of the spool. Can be easily popped out. Fits the Fill3D spools perfectly or any spool with an inner diameter of 52.4mm.
