Work in progress - dimensions may need adjusting - print at your own peril!
After purchasing a small 4 digit LED clock kit, I felt it needed some kind of mount to allow me to secure it to the wall of my cubical.
Designed for the clock to nest securely, allowing access to the adjustment buttons without needing to be removed from the mount.
Should accommodate screws with heads up to 100mm diameter.
May work with other clock kits of a similar nature, but likely will need some tweaks.
