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.Printed at 0.2mm on a Replicator 2 in PLA. Drilled a hole using the same size drill bit as the hole, then screwed into place and washers and nuts used to secure if need be. One didn't need this whereas one did.
