3x3 inch shelf
thingiverse
Small 3x3 inch shelf can be used to hold various items. I'm using it to hold a 24 hour temperature/humidity monitor in my print enclosure. I have it placed about 2/3 up from the base to let me see at a glance what the conditions are inside. Shelf surface has a short 1/8" high ledge to help keep things from slipping off. Three screw holes for mounting and some small brackets supporting the shelf which are not really necessary but visually add to the appearance.
