This model combines a hygrometer mount with a PTFE connector for the Chitu E1 dry box, based on my v1 designs but extensively redesigned for improved filament feeding and a cleaner fit. You can choose between M6 and M10 PTFE fittings (with 1 mm pitch). You can find those fittings on AliExpress and similar sites.
Improvements
Optimized filament path – The original design used a 45° filament path. This version reduces the angle to approximately 10°, creating a smoother, more tangential path that lowers friction and can help prevent feeding issues.
Recessed hygrometer mount – The hygrometer now sits flush with the lid for a cleaner appearance.
Label cutout – Added clearance for the original box label so the mount fits properly without covering it.
Redesigned body – The main part has been redesigned while remaining compatible with the original M6 and M10 nuts.

Credits
This model is inspired by and builds upon the original Chitu E1 hygrometer mount and PTFE connector designs. While the purpose remains the same, the main body has been completely redesigned to improve filament routing, fit, and usability while remaining compatible with the original M6/M10 nuts.
