This is a holder for a grandfather clock winding key that fastens to the column next to the face, and swings out for access. Of course, it may not be the exact form for your clock and key, but you get the idea.
Used PETG, but PLA will work. 0.2mm layers.
Postprocessing, I plan to paint it brown to better match clock.
The author marked this model as their own original creation.
