This design accommodates any clock component kit within 70 x 70 x 35 mm.

The specific movement I used measures 56 x 56 x 29 mm, with a hand shaft diameter of 7.6 mm and a length of 11 mm.

Currently, I’m using double-sided tape to mount it in the ceiling corner.

I hope someone can design a magnetic cover for it—that would make replacing the battery much easier.
