This is a working adaptorplate for the Homematic Kematic HM-Sec-Key.
It is reworked for swedish oval lock cylinders.
If you want to adjust it to another cylinder layout just fill the central hole with solid and carve your own cylinder. Upload and share.
Made from Keymatic manual bitmap, cleaned up bitmap, converted to vector graphics, extruded in tinkercad and terribly hacked with far to many holes and blocks.
Homematic and Keymatic are trademarks of eQ-3 AG
Printed with a .3 mm nozzle and 0.2mm layer
The bolts that "sqeeze" the adaptorplate to the cylinder can be a tight fit, use a M2,5 bolt instead of a M3 bolt.
