Thermometer/Hygrometer Holder for Creality Ender 3 S1 Pro Rail

thingiverse

Made a quick holder to attach a small thermometer/hygrometer to the top rail of a Creality Ender 3 S1 Pro. It holds [these thermo/hygrometers from Amazon.](https://www.amazon.com/gp/product/B07GR65CNT). (Incidentally, these things have been working perfectly since November 2019 with only a battery change, so excellent value for the $9 I spent. These can also switch between C and F if you'd prefer different units.) To hold this to the rail, I recreated a clip that matches the profile on the stock spool holder from Creality rather than simply making a clip that clips over the front and back of the bar. This seems to be more stable and resists sliding from side to side. I made the clip and the holder in two separate pieces so that they can both be printed with a face flat on the bed. They attach together with two #2 x 1/4" self-tapping screws. *This also means you can use the clip as a base for anything you want that you can attach with #2 screws.* The hole in the faceplate is a bit loose, but that makes it easier to pop the unit out if needed.
