I designed and created this hygrometer holder to install on the glass door of my p1s, it is fixed using the original screws. I thought of this solution because, having mounted the handle that allows me to keep the door open when I print, I needed a hygrometer holder that was more detached from the handle to allow me to see it. Printed in PETG leaves plenty of space between the hygrometer and the print bed. I used the supports for hole, but I don't think they are necessary.
