DISCLAIMER: Install at your own risk! I am not responsible for any damages to your 3D printer caused by the installation of this model.

This model is a simple hygrometer holder, designed to be installed using the pre-existing door handle screws for the P1S door. It will probably work for the X1C too assuming the doors are the same… I've printed it using ABS here given temps in the chamber can get quite high. Supports are used and can be easily removed by pushing it out from the top.

It is a very tight fit (41.2mm internal diameter) to ensure the vibrations of the printer will not dislodge the hygrometer during a print. Once installed it is designed to avoid contact with any internal components of the printer, such as the bed. As seen in the uploaded image, there is ample clearance between the holder and the Bambulab PEI plate.
