This is a simple clock stand for the Infinity Instruments Retro Square Wall Clock which can be found at Target, Home Depot, and other retailers online. 

No hardware is required as the clock will press-fit into the stand. However, if you'd like to secure the clock to the stand like I did in the pictures, two M3 screws will do the trick. 

If you'd like to make changes, the stand was designed in OnShape and can be found here:
