A very simple thermometer holder for basic rectangular thermometer sold on AliExpress or Amazon.

I remixed this model (redrew a very basic rectangle on Onshape) without the 2 little pins because they are not compatible with the P1S printer. In this way, it can be used in any printer, using double-sided tape to secure it. Of course, it's possible to use the original model by flipping it, but why not? x)
