These are a couple of little mounts I drew up in CAD quickly to house cheap thermometers I bought for my home brewing setup, to monitor individual temperatures inside a fermentation fridge. The screwon version is designed to screw onto the side of a fridge, with a 4mm (?) metric screw, and the standup version is designed in a way that you can have it sitting on a stand with the probe going either through the back or bottom. The stand up version is designed to have a slip of paper slide in above the gauge, if you wanted to change the name of what you're monitoring. These are designed to fit a cheap eBay thermometer from China, with a mounting dimension (i.e. the hole needed for it to mount into a surround) of 46x27mm. These fit amazingly snugly, but can still be removed if need be.
