Nachbau Homematic Fensterdrehgriffkontakt HM-Sec-RHS - Version mit AA Batterie

thingiverse

Here is my version of a housing for the Homematic window turner contact community replica. ### Update from 01/11/2020 I have added two more versions of the window turner contact: * **FDGK_BatterieAA_Batteriekontakt_mit_Feder_Gehäuse.stl**: The battery holder has been slightly extended, allowing for the installation of battery contacts with a spring (at the negative pole). You will need to print the corresponding cover **FDGK_BatterieAA_Batteriekontakt_mit_Feder_Deckel.stl** * **FDGK_BatterieAA_Batteriekontakt_mit_Feder_Gehäuse_abgerundet.stl**: This is also an extended version (for installing battery contacts with a spring) and the upper area has been rounded to fit better optically with window handles that have a rounded rosette. Again, you will need to print the corresponding cover **FDGK_BatterieAA_Batteriekontakt_mit_Feder_Deckel.stl** ### Original Description It's the version with an AA battery and a step-up converter, see https://forum.fhem.de/index.php/topic,71413.msg642695.html#msg642695 My housing was based on joschi2009's model, which I refined slightly. The original can be found here: https://forum.fhem.de/index.php/topic,71413.msg652849.html#msg652849 And here is the OpenSCAD file of the original: https://forum.fhem.de/index.php/topic,71413.msg958688.html#msg958688 Here's the post for my revised version: https://forum.fhem.de/index.php/topic,71413.msg964267.html#msg964267 In my version, I made the following changes/updates: * The holes for the window turner were horizontally centered so that the handle is symmetrical in the mounted state and looks identical on both left-hand and right-hand windows. * The wall thickness of the cover was increased to make it more stable and easier to print and closer to the box's recess. * Hold-down tabs were added to ensure the cover remains securely attached to the housing and does not fall off when closing the window. * The individual parts are now in three separate files, allowing for separate printing. * The model was redrawn in Fusion 360 (3D model files can be accessed and modified freely).
